Abstract
Systems and methods of the present disclosure include providing higher levels of detail (LODs) for generated three-dimensional (3D) models, such as those represented by neural radiance fields (NeRFs). A 3D model may be presented to a user in which the user may request additional LODs, such as to zoom into the image or to receive information about features within the image. A request to generate finer levels of detail may include using one or more diffusion models to generate images at higher resolutions and/or to hallucinate finer details based on information extracted from the original image or text prompts. Newly generated images may then be added to a set of images associated with the 3D models to enable later model generation to have finer details.

Description
BACKGROUND
In various applications—such as for gaming, animation, or virtual reality content generation, for example—it can be beneficial, if not necessary, to render complex three-dimensional (3D) objects in a way that appears substantially realistic, or at least consistent, to a human viewer. Machine learning has improved the ability to generate novel views of complex 3D scenes, such as by using a neural radiance field (NeRF)-based approach that can render novel views of 3D objects or environments using models of the 3D objects generated from two-dimensional (2D) images of the objects. Additionally, these objects are theoretically non-resolution limited due to their method of generation. However, in practice, optimization processes and the source material for content generation provides limits in resolution, and as a result, trying to reconstruct finer details may lead to blurry or unrealistic images.

For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the embodiments may be practiced without the specific details.

Further, the systems and methods described herein may be used for a variety of purposes, by way of example and without limitation, for machine control, machine locomotion, machine driving, synthetic data generation, model training or updating, perception, augmented reality, virtual reality, mixed reality, robotics, security and surveillance, simulation and digital twinning, autonomous or semi-autonomous machine applications, deep learning, environment simulation, object or actor simulation and/or digital twinning, data center processing, conversational artificial intelligence (AI), generative AI with large language models (LLMs), light transport simulation (e.g., ray-tracing, path tracing, etc.), collaborative content creation for 3D assets, cloud computing and/or any other suitable applications.
Disclosed embodiments may be comprised in a variety of different systems such as automotive systems (e.g., a control system for an autonomous or semi-autonomous machine, a perception system for an autonomous or semi-autonomous machine), systems implemented using a robot, aerial systems, medial systems, boating systems, smart area monitoring systems, systems for performing deep learning operations, systems for performing simulation operations, systems for performing digital twin operations, systems implemented using an edge device, systems incorporating one or more virtual machines (VMs), systems for performing synthetic data generation operations, systems implemented at least partially in a data center, systems for performing conversational AI operations, systems for performing generative AI operations using LLMs, systems for performing light transport simulation, systems for performing collaborative content creation for 3D assets, systems implemented at least partially using cloud computing resources, and/or other types of systems.
Approaches in accordance with various embodiments can be used to improve resolution for one or more three-dimensional (3D) objects or scenes represented by neural radiance fields (NeRFs). A NeRF may be used to learn a plenoptic function (e.g., a five-dimensional (5D) function that takes 3D spatial coordinates and two or more view dependent angles as an input) to output a four-dimensional (4D) radiance field. The 4D radiance-field may be used to show a density and color of a light mass at a given position, when viewed from a certain direction. As a result, the objects represented by the NeRF may capture view dependent effects, such as specularity of the objects. NeRFs may be represented or visualized, for faster learning and rendering, as a grid of voxels where features are stored at corners of the voxels (e.g., such as using octrees as one non-limiting example). When presented with an object, a user or program associated with the object may provide a command to obtain further levels of detail, such as zooming into the object and/or obtaining finer details regarding component parts of the object, among other options. As the level of detail is increased (e.g., a user zooms “into” or “toward” the object), the resolution will be limited by the finite resolution of the images in the set used to generate the NeRF. Systems and methods address this problem by providing for improved resolution at different levels of detail. In at least one embodiment, one or more heuristics may be used to determine that an image is “blurry” (e.g., below a threshold clarity or resolution) and then the image may be provided to a pre-trained image super-resolution model to generate a new, high-resolution image (e.g., a resolution higher than the input image, a resolution higher than a threshold) for the given level of detail. This new image may be provided to the user for viewing and also may be added to augment the set of images used to generate the NeRF, which may then be used to further train or update the NeRF model to generate higher quality images at different levels of detail. Additionally, levels of detail may also refer to particular components forming the object. For example, in at least one embodiment, the NeRF may be used to hallucinate a new image for a finer level of detail, such as by pairing the NeRF with a diffusion model that can take a prompt and then generate a new image. For example, the user may zoom into an image and then provide a prompt regarding information they want to see, such as a prompt to define the image or a region of the image for greater level of detail. The prompt can be provided to a variety of models, such as a large language model or to a pre-defined model or image set with a hierarchy of levels of detail. From there, a diffusion model may be used to generate a new image to provide to the user for viewing, and that image can be added to a set of images to update or finetune the existing NeRF model or to train or update a new NeRF model, which may then enable resulting NeRF models to provide greater levels of detail. In various embodiments, alignment may also be taken into consideration to provide multi-view consistency, such as by selecting different features within images when hallucinating new images. In this manner, finer levels of detail can be generated with the NeRF.
Various systems and methods may be used to form a content generation pipeline that may include one or more diffusion models and/or image super resolution models to optimize a NeRF to generate one or more objects, which may be represented as 3D volumes. For example, the content generation pipeline may be used to generate 3D objects or scenes responsive to requests, such as a prompt or a command to provide a rendering, among other options. Thereafter, a user may interact with the generated object or scene, such as within an interaction environment where the user may perform actions such as panning, rotating, zooming, and the like. As noted herein, while a theoretical resolution of objects generated using NeRFs is potentially infinite, practical considerations, such as the resolution of the images used to train the model, will effectively limit the resolution, and at a point, the objects and/or associated images may become blurry or otherwise be deemed “low(er) resolution.” Systems and methods of the present disclosure address these problems by providing methods to either improve image resolution at certain levels and/or to generate new content showing different levels of detail for a particular image or scene. In at least one embodiment, one or more trained models (e.g., a diffusion model, an image super resolution model, etc.) may form a portion of the pipeline to receive an input (e.g., an image, a prompt, a command, a trigger from one or more workflows, etc.) associated with a certain level of detail for an image. Thereafter, additional levels of detail may be provided using one or more of the models, such as by improving resolution of the image and/or generating a new image associated with a component part of the original image. In this manner, different levels of detail may be generated for various objects and scenes and, moreover, may be used to retrain or improve training data sets for NeRFs and/or other content generation models.
FIG. 1 illustrates an example pipeline 100 that can be used to generate an object 102, such as an object that forms at least a portion of a scene. A set of images 104 may be used to train a NeRF network 106 (which may include one or more diffusion models or various types of image and/or object generation models) to generate different output objects, such as an output based on an input prompt or request. For example, the images may be of one or more objects or scenes taken from different perspectives. Locations and directions for the perspectives may be calculated and used to train the network. In this example, the NeRF network 106 includes one or more neural networks, such as a multilayer perceptron (MLP), but it should be appreciated that other networks may be incorporated into and/or accessible to the NeRF network 106. For example, one or more LLMs may be associated with the NeRF network 106 to receive and process an input prompt. The NeRF network 106 may be used to generate data associated with color 108 and volume density 110, which may be provided to a renderer 112 for generation of the object 202, such as a 3D representation of the object 102.
The object 102 represented by the NeRF may be different from typical representations that use a mesh-based approach (e.g., voxel grids, a polygon mesh, etc.), however, the NeRF can be converted to a mesh using various operations, such as a marching cubes approach. A mesh typically includes faces and vertices, and as a result, may be difficult to manipulate due to the need for different networks to estimate or otherwise determine an appropriate number of faces and vertices to provide a discrete representation of the object. NeRFs, on the other hand, are neural representations of how different points appear from a given camera view, and as a result, lack the faces and vertices common to a mesh representation. The object 102 may be used in a variety of applications, such as for presentation and manipulation within an interaction environment.
In at least one embodiment, the neural fields generated using the NeRF network 106 may be defined for all spatial and/or temporal coordinates, which may be represented as a mapping from a given coordinate to a quantity, such as a scalar, vector, or tensor. In operation, the NeRF network 106 may be trained by sampling coordinates of a scene, for example from the image 104, and providing those coordinates to a neural network to procedure field quantities, which are then sampled for a given reconstruction domain. The reconstruction may then be mapped back to a sensor domain (e.g., a domain that consider depth and normal), which may be a set of 2D RGB images. An error rate may then be calculated to optimize the network. Accordingly, the pipeline for training may include coordinate sampling, neural network processing for a radiance field and reconstruction domain, volume rendering, differentiable forward mapping, and then optimizing for an RGB image and sensor domain. The reconstruction may be a neural field that maps world coordinates to field quantities, while sensor observations (e.g., cameras, microphones, 2D images, etc.) may be transformed into measurements for forward mapping (e.g., volume rendering) to the reconstruction. As noted, the NeRFs may receive a single continuous 5D coordinate as an input to provide spatial location and view direction, which is then fed through an MLP to output corresponding color intensities and volume density. The volume density may be an indication of how much radiance or luminance is accumulated by a ray passing through a given 3D coordinate point and a measure of the effect the given 3D coordinate point has on the overall scene. That is, the volume density is used to determine the likelihood that the predicted color value should be taken into account when rendering the scene/object. During training for NeRFs, the target density and color may not be known, and as a result, these features are mapped back to the input 2D images, compared to ground truth images, and then optimized using a computed loss.
FIG. 2A illustrates an example environment 200 that may be used with embodiments of the present disclosure. The illustrated environment 200 includes an object 202 within an interaction environment 204 that is being viewed by one or more users and/or associated with a content generation pipeline, including but not limited to content generation for video games, AR, VR, MR, online shopping, kiosks, and/or the like. The object 202 may be a portion of a 3D representation of a scene 206, which may include various additional objects or features. In at least one embodiment, the user may interact with the object 202 and/or portions of the scene 206, for example by inputting requests to do things such as rotate to a different viewpoint, pan across, or zoom in, among other options.
Systems and methods of the present disclosure may be directed toward improving a level of detail (LOD) provided for an object and/or scene. The LOD may correspond to a change in an angle of view, which may also be referred to as “zoom” or “zooming” in which, for example, the appearance from a digital camera may represent a change in focal length for the camera with respect to the object 202 or scene 206 from a given position. That is, the LOD may refer to a fine detail interaction with a given object, such that at a first LOD, certain features may not be visible, but when LOD is increased by one or more levels, those same features may be visible. By way of non-limiting example, a pineapple may be visible from a first LOD and be recognizable to a user, but the user may not be able to determine fine details, such as a number of fruitlets on the pineapple, or to be able to read text on a label on the pineapple. By increasing the LOD, the user may view the object as being “closer” and/or portions of the object as being “larger” and, as a result, certain features may appear larger, more prominent, or with greater clarity or precision within a given view area, thereby providing more information and detail for the user to distinguish finer characteristics and features of the pineapple. Accordingly, systems and methods of the present disclosure may be used to generate different LODs for a given object, such as the object 202, rendered using one or more NeRFs, among various other options.
Various embodiments may also refer to LOD with respect to individual characteristics of one or more objects or scenes, which may be a step change and/or based on different features of the object. Returning to the example of a pineapple, LOD may refer to different portions of the pineapple, such as a plant, the fruit itself, fruitlets forming the fruit, seeds, cells of the plant, Deoxyribonucleic acid (DNA) forming the chromosomes, and so forth. In this manner, the LOD may refer to viewings at given pre-defined levels. For example, a first level may correspond to a view of a first level of detail, a request to zoom may move to a second level which shows finer detail associated with a second pre-defined level, and so forth. In other words, the LOD may be presented as a series of nesting dolls or a hierarchy of information, with different levels providing smaller or finer details in a pre-determined fashion. In at least one embodiment, systems and methods may use one or more diffusion or other image generation models to generate these further LODs, for example by pairing such systems with other models, including but not limited to LLMs to parse an input from a user, prepare a prompt for the image generation models, and then use the image generation models to generate and/or define additional LODs. In this manner, pre-defined sets of hierarchical views may be established for different objects, where a step change may be present between different LODs.
FIG. 2B illustrates an example sequence 210 where the LOD goes from a first level 212 to a second level 214 to a third level 216. In this example, the LOD may be changed as a result of the user inputting a command to “zoom” or otherwise modify the angle of view. At the first level 212, the entire object 202 is visible, which in this example remains a pineapple. At the second level 214, only a portion of the object 202 is visible, but now, finer details for the object 202 are shown. For example, a crown 218 from the first level 212 is no longer illustrated, but individual fruitlets 220 are now shown with greater resolution and clarity. In other words, certain regions associated with the command to zoom now appear closer and larger within the view area. Moreover, at the third level 216, even more detail regarding the fruitlets 220 is shown, such as seeds 222 shown within the fruitlets 220.
This level of increasing detail may be desirable in various embodiments, but if the initial resolution to generate the object 202 is below a threshold (e.g., the resolution views from the 2D images used with the NeRF model) the finer details may be blurred or otherwise unclear. For example, the third level 216 illustrates some pixelation/blurring around the seeds 222. Embodiments of the present disclosure may overcome such a problem by identifying the blurriness and/or resolution below a threshold value and then modifying the image, for example using a trained super resolution model, in order to provide a higher resolution image (e.g., an image having a resolution greater than the threshold). Furthermore, systems and methods may also use the newly generated images as input training data for the NeRF, thereby providing higher resolution training images to train the NeRF to generate higher resolution output objects.
FIG. 2C illustrates an example sequence 230 where the LOD goes from a first level 232 to a second level 234, to a third level 236, to a fourth level 238, and to a fifth level 240. In this example, the different levels may correspond to the nesting doll configuration described herein in which the levels are pre-defined for a given object 202. For example, the first level 232 illustrates pineapple plants within a field, the second level 234 illustrates an individual pineapple, the third level 236 illustrates a fruitlet 220, the fourth level 238 illustrates cells 242 of the pineapple, and the fifth level 240 illustrates DNA 242. Such a sequence may be provided as part of a learning module, by way of example only, to illustrate different levels for a given object, such as in a teaching environment. Therefore, the process of “zooming” into the object 202 in the sequence 230 may not change the angle of view, but instead, change the image entirely to show a different level within pre-determined level of details. For example, the sequence 230 of FIG. 2C may be a stored hierarchy that is provided responsive to a request, such as a learning module or within an education series, as an example, that may be generated and prepared for interaction with the user. In at least one embodiment, the sequence 230 may further be provided as an option for a user to explore or otherwise interact with an object formed by a variety of components. By way of another non-limiting example, if an initial object is a car at a first level, a second level may illustrate the engine, a third level may illustrate portions of the engine, such as an exploded view of a piston-cylinder arrangement, and so forth. In this manner, pre-defined hierarchies may be established for interaction and then provided responsive to one or more inputs or prompts.
In various embodiments, one or more of the objects produced in the levels 232-240 may be generated, at least in part, using one or more generative networks, such as a diffusion network. For example, a user may be presented with the first level 232 and wish to know more about the object (e.g., pineapple) shown at the first level 232 and may then provide an action or prompt to go to the second level 234. In at least one embodiment, the action or prompt may be an input, such as scroll wheel to move to the next level or hitting an arrow. In at least one embodiment, the action or prompt may be a textual or voice prompt, such as “what is a pineapple made of?” which may produce different levels of detail, such as the third level 236 to illustrate the individual fruitlets 220. The user may continue to interact to different levels of detail, which may be generated in real or near-real time as the user is interacting with the object. Additionally, and/or alternatively, the different levels may be pre-determined and defined for interaction with the user.
Systems and methods may further be produced in real or near-real time (e.g., without significant delay) to enable a user to interact and/or ask questions about a given object. For example, a user may conduct a conversation with an LLM to ask a series of questions regarding an object and the answers may be used as prompts to generate images or objects, which may be hallucinated using one or more image generation systems. Accordingly, systems and methods may integrate various additional models and then select one or more presentation techniques based on what type of information the user seeks.
Various embodiments of the present disclosure may integrate one or more additional trained models with the NeRF network in order to generate different LODs from an initial generation of the NeRF network. Accordingly, systems and methods may be directed toward a content generation pipeline in which inputs, such as user inputs, may be used to generate finer LODs from an initial object. In at least one embodiment, one or more thresholds may be used to determine when additional networks may be suitable for generating finer details. However, in various embodiments, a pre-defined set of levels may be used.
FIG. 3A illustrates an example environment 300 that may be used with embodiments of the present disclosure to increase a resolution of one or more objects generated using a content generator 302. In this example, an input 304 is provided to the content generator 302, for example a textual input, an auditory prompt, a command request, and/or the like. The input may be from a user interacting with an environment, such as a user that provides a prompt to the environment to produce one or more objects or scenes, which may be 3D objects or scenes, and/or may include audio or video. The prompt may be a textual prompt, such as one provided to a text-to-image generator, a voice prompt, a converted voiced prompt (e.g., a voice prompt that is converted to text), a command prompt (e.g., a command to generate a random image, a command to generate an image specifically trained for the generator), and/or combinations thereof. In at least one embodiment, the input 304 is provided without direct human interaction, such as within a content generation pipeline. For example, an initial control input may be provided, such as “generate a lake scene” and then individual objects may be provided as sub-inputs that are not directly generated by a human or user, such as individual inputs for “lake” or “surrounded by trees” or “add a boat,” and/or the like.
The content generator 302 may include one or more image generation models, which is illustrated as the NeRF model 106 in the example depiction, but may include additional models. Furthermore, the NeRF model 106 may be a representation of several content generation models as one, such as a diffusion model to generate one or more images that can be used to represent an object as a NeRF. The input 304 may be provided to the NeRF model 106, which may generate one or more representations 306 of an object and/or scene responsive to the input. The representation 306 may, for example, correspond to a 3D object viewable from a certain camera view. In at least one embodiment, the representation 306 is provided directly to the renderer 112, which may render the object based, at least in part, on instructions or information associated with the representation 306. However, in one or more embodiments, the representation 306 may first be evaluated by a resolution evaluator 308 prior to rendering. Similarly, the output of the renderer 112 may also be evaluated by the resolution evaluator 308 prior to providing the object 102 for viewing or use by the user.
In at least one embodiment, the resolution evaluator 308 determines whether a resolution or clarity of the representation 306 and/or the object 102 exceeds a threshold level. Resolution may refer to the detail an image holds, and may be measured in a variety of ways that may be used with embodiments of the present disclosure. Resolution may include one or more measurements to quantify how close lines can be to each other and still be visibly resolved, such as by units of line per millimeter or lines per inch(es). Furthermore, measurements may be evaluated by overall image size (e.g., lines per picture height) or by angular subtense. Additionally, line pairs may be used as a measurement of resolution (e.g., line pairs per millimeter). Pixel count is another method to describe resolution (e.g., number of pixel columns by number of pixel rows), where a higher determination of pixels per inch (e.g., the number of pixel columns multiplied by the number of pixel rows) may be indicative of a higher resolution. Another measurement for resolution may be directed toward spatial resolution and its factors, such as a determination of “blurriness” or “sharpness,” which as noted herein may also be a factor of the pixel per inch determination. Furthermore, different resolutions may be set by one or more standards organizations, such as “standard definition” or “high definition,” and/or the like.
In at least one embodiment, the resolution evaluator 308 may determine one or more measurements for an image or image representation corresponding to resolution, such as an evaluation of the pixels per inch from a given view direction. This information may be determined, at least in part, on the images used to generate the representation 306. By way of example, if the initial input images are low resolution images, the resultant output NeRF model is likely also low resolution, at least at finer levels of detail, such as when a user zooms in. Accordingly, systems and methods may determine a resolution associated with the representation 306, and then determine a likely zoom level for the representation to maintain a resolution above a threshold. If a command is received for further levels of detail, then the resolution evaluator 308 may determine that, to maintain image quality, a new image and/or representation should be generated, such as by using a trained image super resolution model 310. In at least one embodiment, a super resolution model may be used to enhance a resolution of from low-resolution to high-resolution, where “low” and “high” are based, at least in part, on a comparison between an initial input and an output. Various models may use degradation functions along with one or more neural networks to find an inverse function of degradation, which may include methods such as pre-upsampling super resolution, post-upsampling super resolution, residual networks, multi-stage residual networks, recursive networks, progressive reconstruction networks, multi-branch networks, attention-based networks, generative models, and/or the like. The super resolution model 310 may then be used to provide an updated representation 312 to the renderer 112 to be presented as the object 102.
As shown in FIG. 3A, various embodiments of the present disclosure may deploy the super resolution model 310 based on an evaluation of the representation 306 from the NeRF model 106 and/or based on an evaluation of an output rendering from the renderer 112. For example, prior to providing the output to the user, the renderer 112 may provide the output object 102 to the resolution evaluator 308, which may make a determination of whether or not the resolution of the output object meets or exceeds a threshold resolution, and then prompt the super resolution model 310 to generate the updated representation 312 for rendering and presentation based on the determination. It should be appreciated that the updated representation 312 may be a single image or a NeRF model or NeRF representation, depending at least on the input provided and the selected method. For example, the updated representation 312 may be provided back to the NeRF model 106 for generation of a new representation 306 using the higher resolution images.
Various embodiments may also improve the NeRF model 106 using images generated by the super resolution model 310. For example, the output of the model (e.g., the representation 312) may also be provided back to the NeRF model 106 for storage and later use, where it may be used as one of the images used to train or generate the representation 306. In this manner, high resolution images may be used for training to generate high resolution representations 306.
FIG. 3B illustrates an example pipeline 320 that may be used with embodiments of the present disclosure. In this example, the input 304A corresponds to a command to render an image and/or object, which in this example is a “pineapple.” The command may be from a user inputting a command, such as to a text-to-image model or from a portion of a workflow to render one or more images or objects for placement within a scene, such as a graphics pipeline for a game that renders objects within a scene based, at least in part, on scene information. Accordingly, systems and methods may be used in embodiments with direct user input and/or input that is responsive to one or more additional commands, among other options and combinations. In this example, the NeRF model 106 may generate the output 102A, corresponding to an image of a pineapple. The pineapple may be generated using one or more trained machine learning systems, for example as a 2D or 3D object for placement within a scene.
Another input 304B is received corresponding to a command to “zoom” or change an angle of viewing of the object 102A. For example, the object 102A may be presented to the user, for example using a renderer that may provide a visible representation of the object within an environment. The user and/or a workflow may present the second command 304B to zoom into the object 102A, which may be a command to provide greater fine level detail for one or more features forming the object 102A. The zoom command may be a user command, such as using a scroll wheel or a combination of keyboard commands, or the zoom command may be responsive to one or more other commands, such as a user selecting an object within a video game and then a workflow executing zooming in toward the object to provide finer detail, among other options. The second object 102B may be prepared for rendering and presentation to the user, as noted herein, but may also, either prior to or after the rendering, undergo one or more resolution evaluations, such as using the evaluator 308. The evaluator 308 may determine one or more measurable aspects of the second object 102B to determine whether the second object 102B meets and/or exceeds a threshold value. For example, the pixels per inch may be determined for the second object 102B and compared against a threshold, which may be determined based, at least in part, on one or more properties of the compute device being used by the user to view the object. For example, if it is determined the user has an ultra-high definition monitor, then the threshold may be greater than a user operating with a standard definition monitor. In another example, the settings the user has selected for execution of the environment may also be used to determine the threshold, among other options.
Along a first path, marked as “1,” it may be determined that the resolution of the second object 102B meets or exceeds the threshold, and therefore, the second object may be prepared for rendering and/or presented to the user. Along a second path, marked as “2,” it may be determined that the resolution of the second object 102B does not meet or exceed the threshold, and therefore, the super resolution model 310 may be used to increase or otherwise enhance resolution and generate a third object 102C (as an image for the NeRF model 106 and/or as a singular image for presentation), which may be further evaluated, marked as “3,” and then, if the resolution meets or exceeds the threshold, may be presented to the user, marked as “4” or may be processed further along the second path, marked as “2.” In this manner, additional commands may be received and then resolutions may be checked, and additional objects may be generated responsive to the results of the resolution evaluations.
FIG. 4A illustrates an example environment 400 that may be used with embodiments of the present disclosure to generate content using one or more models responsive to a request to increase an LOD. Various embodiments include the LLM 310 and/or the NeRF model 106, and may further include one or more image generation models, such as a diffusion model. In this example, an input 304 is provided to the LLM 310, such as a question regarding an object visible to the user. For example, the user may view the object and ask particular questions about its composition, such as when paired within an educational program. The LLM 310 may receive the input and generate a prompt 402, which may be passed to the NeRF model 106, which in at least one embodiment includes a diffusion model, to generate the object 102. In this manner, the user may provide input regarding an image or object and additional details may be hallucinated by the one or more models to generate further information that is, in at least some embodiments, not present within an original object.
FIG. 4B illustrates an example pipeline 420 that may be used with embodiments of the present disclosure. In this example, a starting object 422 is provided to the user, which may be an object generated by one or more trained models and/or may be an object that has been selected as the start of a series of object at pre-determined levels, as noted herein. The input 304A in this example is in the form of a question, asking what type of field is shown in the starting object 422. The input 304A is provided to the LLM 310, which may determine information associated with the image, for example where the LLM 310 is a multi-modal model that can evaluate an image and provide a response regarding one or more objects within the image, and may generate the prompt 402A corresponding to “pineapple,” as the answer to the input 304A. The NeRF model 106 may then receive the prompt 402A to generate the object 102A, which corresponds to a pineapple. In at least one embodiment, the object 102A includes a level of detail to allow interaction by the user, such as zooming or otherwise looking at different features. The user may zoom into the output 102A to form a second object 102B, which may be from a different view direction or angle, and may generate a second input 304B directed toward features of the second object 102B. For example, the second input 304B may be a question, such as “What is the pineapple made of?”, which may be provided back to the LLM 310 to generate a second prompt 304B to answer the question. The second prompt 304B answers that the pineapple is made of fruitlets, which is then provided to the NeRF model 106 to generate a third object 102C corresponding to the fruitlets. Additional questions may then be routed back to the LLM 310, thereby enabling different levels of detail for various interactions.
FIG. 5A illustrates an example process 500 that can be used to generate new frames for greater LOD and to update a set of training images. It should be understood that for this and other processes presented herein that there may be additional, fewer, or alternative operations performed in similar or alternative orders, or at least partially in parallel, within the scope of the various embodiments unless otherwise specifically stated. Further, while this example refers to NeRFs and generation of content using prompts, using diffusion models, it should be understood that various other such tasks can benefit from aspects of the various embodiments and that a variety of different model representations and/or generative models may also be used. In this example, a target level of detail for a 3D volume is determined 502. The 3D volume may be associated with a NeRF, but various embodiments may also be used with other 3D volumes that can be converted to NeRFs and/or from 3D volumes that are converted from NeRFs. A current view, which may be a frame or a view of the 3D volume, representing the 3D volume, may be provided to an image generation network 504. The image generation network may include one or more trained models, such as diffusion models, that may take an input image or command and generate one or more images associated with the input image or command. By way of example, a text-to-image model may take an input text prompt and generate an image associated with that prompt. Similarly, a super-resolution image model may take an input image and then generate an output image having a higher resolution. An updated view, representing the 3D volume, may be generated using the current view 506 and provided for viewing 508, such as to a user. The updated view may then be added to a set of images associated with the 3D volume 510, which may then train the 3D volume and/or a model associated with the 3D volume to generate additional images and/or views using the newly generated images 512.
FIG. 5B illustrates an example process 520 for generating an object responsive to a request. In this example, a request is received to generate an object using a NeRF 522. The request may include an associated prompt or command, such as a particular question associated with an object and/or a command to perform one or more actions to the object. From the prompt, a level of detailed for the object may be determined 524. For example, the level of detail may be associated with a viewing angle, a feature of the object, and/or combinations thereof. An object at the target level of detail may be generated 526, such as by using one or more diffusion models. The generated object may then be provided responsive to the request 528.
FIG. 5C illustrates an example process 540 for generating an object at a higher level of detail responsive to a request. In this example, a command to change a level of detail for an object is received 542. For example, a user may input a command to zoom in (e.g., change an angle of view) for an object, which may be a 3D object represented by a NeRF. Additionally, a command to decrease a level of detail may also be provided, for example to illustrate how one or more components fit within a system. A representation of the object may be generated at the target level of detail 544 and a resolution for that representation, at the target level of detail, may be determined 546. For example, a number of pixels per inch may be determined for the representation.
In at least one embodiment, the resolution may be compared to a threshold 548. If the resolution exceeds the threshold, a visual representation of the object may be presented at the target level of detail 550. If the resolution is less than the threshold, then the representation may be provided to a trained super-resolution 552, which may generate a second representation of the object at a higher resolution 554. Optionally, the higher resolution second representation may then be evaluated to determine a second resolution for the second representation 556, and the second representation may be compared against the threshold, with the process repeating until a stop condition is reached.
As discussed, aspects of various approaches presented herein can be lightweight enough to execute on a device such as a client device, such as a personal computer or gaming console, in real time. Such processing can be performed on, or for, content that is generated on, or received by, that client device or received from an external source, such as streaming data or other content received over at least one network. In some instances, the processing and/or determination of this content may be performed by one of these other devices, systems, or entities, then provided to the client device (or another such recipient) for presentation or another such use.
As an example, FIG. 6 illustrates an example network configuration 600 that can be used to provide, generate, modify, encode, process, and/or transmit image data or other such content. In at least one embodiment, a client device 602 can generate or receive data for a session using components of a control application 604 on client device 602 and data stored locally on that client device. In at least one embodiment, a content application 624 executing on a server 620 (e.g., a cloud server or edge server) may initiate a session associated with at least one client device 602, as may utilize a session manager and user data stored in a user database 636, and can cause content such as one or more digital assets (e.g., object representations) from an asset repository 634 to be determined by a content manager 626. A content manager 626 may work with an image synthesis module 628 to generate or synthesize new objects, digital assets, or other such content to be provided for presentation via the client device 602. In at least one embodiment, this image synthesis module 628 can use one or more neural networks, or machine learning models, which can be trained or updated using a training module 632 or system that is on, or in communication with, the server 620. This can include training and/or using a diffusion model 630 to generate content tiles that can be used by an image synthesis module 628, for example, to apply a non-repeating texture to a region of an environment for which image or video data is to be presented via a client device 602. At least a portion of the generated content may be transmitted to the client device 602 using an appropriate transmission manager 622 to send by download, streaming, or another such transmission channel. An encoder may be used to encode and/or compress at least some of this data before transmitting to the client device 602. In at least one embodiment, the client device 602 receiving such content can provide this content to a corresponding control application 604, which may also or alternatively include a graphical user interface 610, content manager 612, and image synthesis or diffusion module 614 for use in providing, synthesizing, modifying, or using content for presentation (or other purposes) on or by the client device 602. A decoder may also be used to decode data received over the network(s) 640 for presentation via client device 602, such as image or video content through a display 606 and audio, such as sounds and music, through at least one audio playback device 608, such as speakers or headphones. In at least one embodiment, at least some of this content may already be stored on, rendered on, or accessible to client device 602 such that transmission over network 640 is not required for at least that portion of content, such as where that content may have been previously downloaded or stored locally on a hard drive or optical disk. In at least one embodiment, a transmission mechanism such as data streaming can be used to transfer this content from server 620, or user database 636, to client device 602. In at least one embodiment, at least a portion of this content can be obtained, enhanced, and/or streamed from another source, such as a third party service 660 or other client device 650, that may also include a content application 662 for generating, enhancing, or providing content. In at least one embodiment, portions of this functionality can be performed using multiple computing devices, or multiple processors within one or more computing devices, such as may include a combination of CPUs and GPUs.
In this example, these client devices can include any appropriate computing devices, as may include a desktop computer, notebook computer, set-top box, streaming device, gaming console, smartphone, tablet computer, VR headset, AR goggles, wearable computer, or a smart television. Each client device can submit a request across at least one wired or wireless network, as may include the Internet, an Ethernet, a local area network (LAN), or a cellular network, among other such options. In this example, these requests can be submitted to an address associated with a cloud provider, who may operate or control one or more electronic resources in a cloud provider environment, such as may include a data center or server farm. In at least one embodiment, the request may be received or processed by at least one edge server, that sits on a network edge and is outside at least one security layer associated with the cloud provider environment. In this way, latency can be reduced by enabling the client devices to interact with servers that are in closer proximity, while also improving security of resources in the cloud provider environment.
In at least one embodiment, such a system can be used for performing graphical rendering operations. In other embodiments, such a system can be used for other purposes, such as for providing image or video content to test or validate autonomous machine applications, or for performing deep learning operations. In at least one embodiment, such a system can be implemented using an edge device, or may incorporate one or more Virtual Machines (VMs). In at least one embodiment, such a system can be implemented at least partially in a data center or at least partially using cloud computing resources.

In at least one embodiment, a training pipeline may include a scenario where facility 1302 needs a machine learning model for use in performing one or more processing tasks for one or more applications in deployment system 1306, but facility 1302 may not currently have such a machine learning model (or may not have a model that is optimized, efficient, or effective for such purposes). In at least one embodiment, an existing machine learning model may be selected from a model registry 1324. In at least one embodiment, model registry 1324 may include machine learning models trained to perform a variety of different inference tasks on imaging data. In at least one embodiment, machine learning models in model registry 1324 may have been trained on imaging data from different facilities than facility 1302 (e.g., facilities remotely located). In at least one embodiment, machine learning models may have been trained on imaging data from one location, two locations, or any number of locations. In at least one embodiment, when being trained on imaging data from a specific location, training may take place at that location, or at least in a manner that protects confidentiality of imaging data or restricts imaging data from being transferred off-premises. In at least one embodiment, once a model is trained—or partially trained—at one location, a machine learning model may be added to model registry 1324. In at least one embodiment, a machine learning model may then be retrained, or updated, at any number of other facilities, and a retrained or updated model may be made available in model registry 1324. In at least one embodiment, a machine learning model may then be selected from model registry 1324—and referred to as output model(s) 1316—and may be used in deployment system 1306 to perform one or more processing tasks for one or more applications of a deployment system.
In at least one embodiment, a scenario may include facility 1302 requiring a machine learning model for use in performing one or more processing tasks for one or more applications in deployment system 1306, but facility 1302 may not currently have such a machine learning model (or may not have a model that is optimized, efficient, or effective for such purposes). In at least one embodiment, a machine learning model selected from model registry 1324 may not be fine-tuned or optimized for imaging data 1308 generated at facility 1302 because of differences in populations, robustness of training data used to train a machine learning model, diversity in anomalies of training data, and/or other issues with training data. In at least one embodiment, AI-assisted annotation 1310 may be used to aid in generating annotations corresponding to imaging data 1308 to be used as ground truth data for retraining or updating a machine learning model. In at least one embodiment, labeled data 1312 may be used as ground truth data for training a machine learning model. In at least one embodiment, retraining or updating a machine learning model may be referred to as model training 1314. In at least one embodiment, model training 1314—e.g., AI-assisted annotation 1310, labeled data 1312, or a combination thereof—may be used as ground truth data for retraining or updating a machine learning model. In at least one embodiment, a trained machine learning model may be referred to as output model(s) 1316, and may be used by deployment system 1306, as described herein.
In at least one embodiment, deployment system 1306 may include software 1318, services 1320, hardware 1322, and/or other components, features, and functionality. In at least one embodiment, deployment system 1306 may include a software “stack,” such that software 1318 may be built on top of services 1320 and may use services 1320 to perform some or all of processing tasks, and services 1320 and software 1318 may be built on top of hardware 1322 and use hardware 1322 to execute processing, storage, and/or other compute tasks of deployment system 1306. In at least one embodiment, software 1318 may include any number of different containers, where each container may execute an instantiation of an application. In at least one embodiment, each application may perform one or more processing tasks in an advanced processing and inferencing pipeline (e.g., inferencing, object detection, feature detection, segmentation, image enhancement, calibration, etc.). In at least one embodiment, an advanced processing and inferencing pipeline may be defined based on selections of different containers that are desired or required for processing imaging data 1308, in addition to containers that receive and configure imaging data for use by each container and/or for use by facility 1302 after processing through a pipeline (e.g., to convert outputs back to a usable data type). In at least one embodiment, a combination of containers within software 1318 (e.g., that make up a pipeline) may be referred to as a virtual instrument (as described in more detail herein), and a virtual instrument may leverage services 1320 and hardware 1322 to execute some or all processing tasks of applications instantiated in containers.
In at least one embodiment, a data processing pipeline may receive input data (e.g., imaging data 1308) in a specific format in response to an inference request (e.g., a request from a user of deployment system 1306). In at least one embodiment, input data may be representative of one or more images, video, and/or other data representations generated by one or more imaging devices. In at least one embodiment, data may undergo pre-processing as part of data processing pipeline to prepare data for processing by one or more applications. In at least one embodiment, post-processing may be performed on an output of one or more inferencing tasks or other processing tasks of a pipeline to prepare an output data for a next application and/or to prepare output data for transmission and/or use by a user (e.g., as a response to an inference request). In at least one embodiment, inferencing tasks may be performed by one or more machine learning models, such as trained or deployed neural networks, which may include output model(s) 1316 of training system 1304.
In at least one embodiment, tasks of data processing pipeline may be encapsulated in a container(s) that each represents a discrete, fully functional instantiation of an application and virtualized computing environment that is able to reference machine learning models. In at least one embodiment, containers or applications may be published into a private (e.g., limited access) area of a container registry (described in more detail herein), and trained or deployed models may be stored in model registry 1324 and associated with one or more applications. In at least one embodiment, images of applications (e.g., container images) may be available in a container registry, and once selected by a user from a container registry for deployment in a pipeline, an image may be used to generate a container for an instantiation of an application for use by a user's system.
In at least one embodiment, developers (e.g., software developers, clinicians, doctors, etc.) may develop, publish, and store applications (e.g., as containers) for performing image processing and/or inferencing on supplied data. In at least one embodiment, development, publishing, and/or storing may be performed using a software development kit (SDK) associated with a system (e.g., to ensure that an application and/or container developed is compliant with or compatible with a system). In at least one embodiment, an application that is developed may be tested locally (e.g., at a first facility, on data from a first facility) with an SDK which may support at least some of services 1320 as a system (e.g., system 1200 of FIG. 12). In at least one embodiment, because DICOM objects may contain anywhere from one to hundreds of images or other data types, and due to a variation in data, a developer may be responsible for managing (e.g., setting constructs for, building pre-processing into an application, etc.) extraction and preparation of incoming data. In at least one embodiment, once validated by system 1300 (e.g., for accuracy), an application may be available in a container registry for selection and/or implementation by a user to perform one or more processing tasks with respect to data at a facility (e.g., a second facility) of a user.
In at least one embodiment, developers may then share applications or containers through a network for access and use by users of a system (e.g., system 1300 of FIG. 13). In at least one embodiment, completed and validated applications or containers may be stored in a container registry and associated machine learning models may be stored in model registry 1324. In at least one embodiment, a requesting entity—who provides an inference or image processing request—may browse a container registry and/or model registry 1324 for an application, container, dataset, machine learning model, etc., select a desired combination of elements for inclusion in data processing pipeline, and submit an imaging processing request. In at least one embodiment, a request may include input data (and associated patient data, in some examples) that is necessary to perform a request, and/or may include a selection of application(s) and/or machine learning models to be executed in processing a request. In at least one embodiment, a request may then be passed to one or more components of deployment system 1306 (e.g., a cloud) to perform processing of data processing pipeline. In at least one embodiment, processing by deployment system 1306 may include referencing selected elements (e.g., applications, containers, models, etc.) from a container registry and/or model registry 1324. In at least one embodiment, once results are generated by a pipeline, results may be returned to a user for reference (e.g., for viewing in a viewing application suite executing on a local, on-premises workstation or terminal).
In at least one embodiment, to aid in processing or execution of applications or containers in pipelines, services 1320 may be leveraged. In at least one embodiment, services 1320 may include compute services, artificial intelligence (AI) services, visualization services, and/or other service types. In at least one embodiment, services 1320 may provide functionality that is common to one or more applications in software 1318, so functionality may be abstracted to a service that may be called upon or leveraged by applications. In at least one embodiment, functionality provided by services 1320 may run dynamically and more efficiently, while also scaling well by allowing applications to process data in parallel (e.g., using a parallel computing platform 1230 (FIG. 12)). In at least one embodiment, rather than each application that shares a same functionality offered by services 1320 being required to have a respective instance of services 1320, services 1320 may be shared between and among various applications. In at least one embodiment, services may include an inference server or engine that may be used for executing detection or segmentation tasks, as non-limiting examples. In at least one embodiment, a model training service may be included that may provide machine learning model training and/or retraining capabilities.

In at least one embodiment, a visualization service may be used that may add image rendering effects—such as ray-tracing, rasterization, denoising, sharpening, etc.—to add realism to two-dimensional (2D) and/or three-dimensional (3D) models. In at least one embodiment, virtual instrument services may be included that provide for beam-forming, segmentation, inferencing, imaging, and/or support for other applications within pipelines of virtual instruments.
In at least one embodiment, where services 1320 includes an AI service (e.g., an inference service), one or more machine learning models may be executed by calling upon (e.g., as an API call) an inference service (e.g., an inference server) to execute machine learning model(s), or processing thereof, as part of application execution. In at least one embodiment, where another application includes one or more machine learning models for segmentation tasks, an application may call upon an inference service to execute machine learning models for performing one or more of processing operations associated with segmentation tasks. In at least one embodiment, software 1318 implementing advanced processing and inferencing pipeline that includes segmentation application and anomaly detection application may be streamlined because each application may call upon a same inference service to perform one or more inferencing tasks.
In at least one embodiment, hardware 1322 may include GPUs, CPUs, graphics cards, an AI/deep learning system (e.g., an AI supercomputer, such as NVIDIA's DGX), a cloud platform, or a combination thereof. In at least one embodiment, different types of hardware 1322 may be used to provide efficient, purpose-built support for software 1318 and services 1320 in deployment system 1306. In at least one embodiment, use of GPU processing may be implemented for processing locally (e.g., at facility 1302), within an AI/deep learning system, in a cloud system, and/or in other processing components of deployment system 1306 to improve efficiency, accuracy, and efficacy of image processing and generation. In at least one embodiment, software 1318 and/or services 1320 may be optimized for GPU processing with respect to deep learning, machine learning, and/or high-performance computing, as non-limiting examples. In at least one embodiment, at least some of computing environment of deployment system 1306 and/or training system 1304 may be executed in a datacenter one or more supercomputers or high performance computing systems, with GPU optimized software (e.g., hardware and software combination of NVIDIA's DGX System).

In at least one embodiment, any combination of tasks within training system 1304 may be used depending on what is required for each respective machine learning model. In at least one embodiment, one or more of machine learning models may already be trained and ready for deployment so machine learning models may not undergo any processing by training system 1304, and may be implemented by deployment system 1306.
In at least one embodiment, output model(s) 1316 and/or pre-trained models 1406 may include any types of machine learning models depending on implementation or embodiment.

In at least one embodiment, for each instance of imaging data 1308 (or other data type used by machine learning models), there may be corresponding ground truth data generated by training system 1304. In at least one embodiment, AI-assisted annotation may be performed as part of deployment pipeline(s) 1410; either in addition to, or in lieu of AI-assisted annotation included in training pipelines 1404.

In at least one embodiment, applications may then call or execute one or more services 1320 for performing compute, AI, or visualization tasks associated with respective applications, and software 1318 and/or services 1320 may leverage hardware 1322 to perform processing tasks in an effective and efficient manner. In at least one embodiment, communications sent to, or received by, a training system 1304 and a deployment system 1306 may occur using a pair of DICOM adapters 1402A, 1402B.

In at least one embodiment, for a single device, there may be more than one deployment pipeline(s) 1410 depending on information desired from data generated by a device. In at least one embodiment, where detections of anomalies are desired from an MRI machine, there may be a first deployment pipeline(s) 1410, and where image enhancement is desired from output of an MRI machine, there may be a second deployment pipeline(s) 1410.
In at least one embodiment, an image generation application may include a processing task that includes use of a machine learning model. In at least one embodiment, a user may desire to use their own machine learning model, or to select a machine learning model from model registry 1324. In at least one embodiment, a user may implement their own machine learning model or select a machine learning model for inclusion in an application for performing a processing task. In at least one embodiment, applications may be selectable and customizable, and by defining constructs of applications, deployment and implementation of applications for a particular user are presented as a more seamless user experience. In at least one embodiment, by leveraging other features of system 1400—δsuch as services 1320 and hardware 1322—deployment pipeline(s) 1410 may be even more user friendly, provide for easier integration, and produce more accurate, efficient, and timely results.
In at least one embodiment, deployment system 1306 may include a user interface (“UI”) 1414 (e.g., a graphical user interface, a web interface, etc.) that may be used to select applications for inclusion in deployment pipeline(s) 1410, arrange applications, modify or change applications or parameters or constructs thereof, use and interact with deployment pipeline(s) 1410 during set-up and/or deployment, and/or to otherwise interact with deployment system 1306. In at least one embodiment, although not illustrated with respect to training system 1304, UI 1414 (or a different user interface) may be used for selecting models for use in deployment system 1306, for selecting models for training, or retraining, in training system 1304, and/or for otherwise interacting with training system 1304.
In at least one embodiment, pipeline manager 1412 may be used, in addition to an application orchestration system 1428, to manage interaction between applications or containers of deployment pipeline(s) 1410 and services 1320 and/or hardware 1322. In at least one embodiment, pipeline manager 1412 may be configured to facilitate interactions from application to application, from application to services 1320, and/or from application or service to hardware 1322. In at least one embodiment, although illustrated as included in software 1318, this is not intended to be limiting, and in some examples pipeline manager 1412 may be included in services 1320. In at least one embodiment, application orchestration system 1428 (e.g., Kubernetes, DOCKER, etc.) may include a container orchestration system that may group applications into containers as logical units for coordination, management, scaling, and deployment. In at least one embodiment, by associating applications from deployment pipeline(s) 1410 (e.g., a reconstruction application, a segmentation application, etc.) with individual containers, each application may execute in a self-contained environment (e.g., at a kernel level) to increase speed and efficiency.
In at least one embodiment, each application and/or container (or image thereof) may be individually developed, modified, and deployed (e.g., a first user or developer may develop, modify, and deploy a first application and a second user or developer may develop, modify, and deploy a second application separate from a first user or developer), which may allow for focus on, and attention to, a task of a single application and/or container(s) without being hindered by tasks of another application(s) or container(s). In at least one embodiment, communication, and cooperation between different containers or applications may be aided by pipeline manager 1412 and application orchestration system 1428. In at least one embodiment, so long as an expected input and/or output of each container or application is known by a system (e.g., based on constructs of applications or containers), application orchestration system 1428 and/or pipeline manager 1412 may facilitate communication among and between, and sharing of resources among and between, each of applications or containers. In at least one embodiment, because one or more of applications or containers in deployment pipeline(s) 1410 may share same services and resources, application orchestration system 1428 may orchestrate, load balance, and determine sharing of services or resources between and among various applications or containers. In at least one embodiment, a scheduler may be used to track resource requirements of applications or containers, current usage or planned usage of these resources, and resource availability. In at least one embodiment, a scheduler may thus allocate resources to different applications and distribute resources between and among applications in view of requirements and availability of a system. In some examples, a scheduler (and/or other component of application orchestration system 1428) may determine resource availability and distribution based on constraints imposed on a system (e.g., user constraints), such as quality of service (QOS), urgency of need for data outputs (e.g., to determine whether to execute real-time processing or delayed processing), etc.
In at least one embodiment, services 1320 leveraged by and shared by applications or containers in deployment system 1306 may include compute service(s) 1416, AI service(s) 1418, visualization service(s) 1420, and/or other service types. In at least one embodiment, applications may call (e.g., execute) one or more of services 1320 to perform processing operations for an application. In at least one embodiment, compute service(s) 1416 may be leveraged by applications to perform super-computing or other high-performance computing (HPC) tasks. In at least one embodiment, compute service(s) 1416 may be leveraged to perform parallel processing (e.g., using a parallel computing platform 1430) for processing data through one or more of applications and/or one or more tasks of a single application, substantially simultaneously. In at least one embodiment, parallel computing platform 1430 (e.g., NVIDIA's CUDA) may enable general purpose computing on GPUs (GPGPU) (e.g., GPUs/Graphics 1422). In at least one embodiment, a software layer of parallel computing platform 1430 may provide access to virtual instruction sets and parallel computational elements of GPUs, for execution of compute kernels. In at least one embodiment, parallel computing platform 1430 may include memory and, in some embodiments, a memory may be shared between and among multiple containers, and/or between and among different processing tasks within a single container. In at least one embodiment, inter-process communication (IPC) calls may be generated for multiple containers and/or for multiple processes within a container to use same data from a shared segment of memory of parallel computing platform 1430 (e.g., where multiple different stages of an application or multiple applications are processing same information). In at least one embodiment, rather than making a copy of data and moving data to different locations in memory (e.g., a read/write operation), same data in same location of a memory may be used for any number of processing tasks (e.g., at a same time, at different times, etc.). In at least one embodiment, as data is used to generate new data as a result of processing, this information of a new location of data may be stored and shared between various applications. In at least one embodiment, location of data and a location of updated or modified data may be part of a definition of how a payload is understood within containers.
In at least one embodiment, AI service(s) 1418 may be leveraged to perform inferencing services for executing machine learning model(s) associated with applications (e.g., tasked with performing one or more processing tasks of an application). In at least one embodiment, AI service(s) 1418 may leverage AI system 1424 to execute machine learning model(s) (e.g., neural networks, such as CNNs) for segmentation, reconstruction, object detection, feature detection, classification, and/or other inferencing tasks. In at least one embodiment, applications of deployment pipeline(s) 1410 may use one or more of output model(s) 1316 from training system 1304 and/or other models of applications to perform inference on imaging data. In at least one embodiment, two or more examples of inferencing using application orchestration system 1428 (e.g., a scheduler) may be available. In at least one embodiment, a first category may include a high priority/low latency path that may achieve higher service level agreements, such as for performing inference on urgent requests during an emergency, or for a radiologist during diagnosis. In at least one embodiment, a second category may include a standard priority path that may be used for requests that may be non-urgent or where analysis may be performed at a later time. In at least one embodiment, application orchestration system 1428 may distribute resources (e.g., services 1320 and/or hardware 1322) based on priority paths for different inferencing tasks of AI service(s) 1418.
In at least one embodiment, shared storage may be mounted to AI service(s) 1418 within system 1400. In at least one embodiment, shared storage may operate as a cache (or other storage device type) and may be used to process inference requests from applications. In at least one embodiment, when an inference request is submitted, a request may be received by a set of API instances of deployment system 1306, and one or more instances may be selected (e.g., for best fit, for load balancing, etc.) to process a request. In at least one embodiment, to process a request, a request may be entered into a database, a machine learning model may be located from model registry 1324 if not already in a cache, a validation step may ensure appropriate machine learning model is loaded into a cache (e.g., shared storage), and/or a copy of a model may be saved to a cache. In at least one embodiment, a scheduler (e.g., of pipeline manager 1412) may be used to launch an application that is referenced in a request if an application is not already running or if there are not enough instances of an application. In at least one embodiment, if an inference server is not already launched to execute a model, an inference server may be launched. Any number of inference servers may be launched per model. In at least one embodiment, in a pull model, in which inference servers are clustered, models may be cached whenever load balancing is advantageous. In at least one embodiment, inference servers may be statically loaded in corresponding, distributed servers.
In at least one embodiment, inferencing may be performed using an inference server that runs in a container. In at least one embodiment, an instance of an inference server may be associated with a model (and optionally a plurality of versions of a model). In at least one embodiment, if an instance of an inference server does not exist when a request to perform inference on a model is received, a new instance may be loaded.

In at least one embodiment, results may be stored in a data store as training data 1538 and used as (for example and without limitation) ground truth data for training. In at least one embodiment, when computing device 1508 sends extreme points for AI-assisted annotation, a deep learning model, for example, may receive this data as input and return inference results of a segmented organ or abnormality.

Other variations are within spirit of present disclosure. Thus, while disclosed techniques are susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in drawings and have been described above in detail. It should be understood, however, that there is no intention to limit disclosure to specific form or forms disclosed, but on contrary, intention is to cover all modifications, alternative constructions, and equivalents falling within spirit and scope of disclosure, as defined in appended claims.
Use of terms “a” and “an” and “the” and similar referents in context of describing disclosed embodiments (especially in context of following claims) are to be construed to cover both singular and plural, unless otherwise indicated herein or clearly contradicted by context, and not as a definition of a term. Terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (meaning “including, but not limited to,”) unless otherwise noted. Term “connected,” when unmodified and referring to physical connections, is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within range, unless otherwise indicated herein and each separate value is incorporated into specification as if it were individually recited herein. Use of term “set” (e.g., “a set of items”) or “subset,” unless otherwise noted or contradicted by context, is to be construed as a nonempty collection comprising one or more members. Further, unless otherwise noted or contradicted by context, term “subset” of a corresponding set does not necessarily denote a proper subset of corresponding set, but subset and corresponding set may be equal.
Conjunctive language, such as phrases of form “at least one of A, B, and C,” or “at least one of A, B and C,” unless specifically stated otherwise or otherwise clearly contradicted by context, is otherwise understood with context as used in general to present that an item, term, etc., may be either A or B or C, or any nonempty subset of set of A and B and C. For instance, in illustrative example of a set having three members, conjunctive phrases “at least one of A, B, and C” and “at least one of A, B and C” refer to any of following sets: {A}, {B}, {C}, {A, B}, {A, C}, {B, C}, {A, B, C}. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of A, at least one of B, and at least one of C each to be present. In addition, unless otherwise noted or contradicted by context, term “plurality” indicates a state of being plural (e.g., “a plurality of items” indicates multiple items). A plurality is at least two items, but can be more when so indicated either explicitly or by context. Further, unless stated otherwise or otherwise clear from context, phrase “based on” means “based at least in part on” and not “based solely on.”
Operations of processes described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. In at least one embodiment, a process such as those processes described herein (or variations and/or combinations thereof) is performed under control of one or more computer systems configured with executable instructions and is implemented as code (e.g., executable instructions, one or more computer programs or one or more applications) executing collectively on one or more processors, by hardware or combinations thereof. In at least one embodiment, code is stored on a computer-readable storage medium, for example, in form of a computer program comprising a plurality of instructions executable by one or more processors. In at least one embodiment, a computer-readable storage medium is a non-transitory computer-readable storage medium that excludes transitory signals (e.g., a propagating transient electric or electromagnetic transmission) but includes non-transitory data storage circuitry (e.g., buffers, cache, and queues) within transceivers of transitory signals. In at least one embodiment, code (e.g., executable code or source code) is stored on a set of one or more non-transitory computer-readable storage media having stored thereon executable instructions (or other memory to store executable instructions) that, when executed (i.e., as a result of being executed) by one or more processors of a computer system, cause computer system to perform operations described herein. A set of non-transitory computer-readable storage media, in at least one embodiment, comprises multiple non-transitory computer-readable storage media and one or more of individual non-transitory storage media of multiple non-transitory computer-readable storage media lack all of code while multiple non-transitory computer-readable storage media collectively store all of code. In at least one embodiment, executable instructions are executed such that different instructions are executed by different processors-for example, a non-transitory computer-readable storage medium store instructions and a main central processing unit (“CPU”) executes some of instructions while a graphics processing unit (“GPU”) executes other instructions. In at least one embodiment, different components of a computer system have separate processors and different processors execute different subsets of instructions.
Accordingly, in at least one embodiment, computer systems are configured to implement one or more services that singly or collectively perform operations of processes described herein and such computer systems are configured with applicable hardware and/or software that enable performance of operations. Further, a computer system that implements at least one embodiment of present disclosure is a single device and, in another embodiment, is a distributed computer system comprising multiple devices that operate differently such that distributed computer system performs operations described herein and such that a single device does not perform all operations.
Use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate embodiments of disclosure and does not pose a limitation on scope of disclosure unless otherwise claimed. No language in specification should be construed as indicating any non-claimed element as essential to practice of disclosure.
All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.
In description and claims, terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms may be not intended as synonyms for each other. Rather, in particular examples, “connected” or “coupled” may be used to indicate that two or more elements are in direct or indirect physical or electrical contact with each other. “Coupled” may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.
Unless specifically stated otherwise, it may be appreciated that throughout specification terms such as “processing,” “computing,” “calculating,” “determining,” or like, refer to action and/or processes of a computer or computing system, or similar electronic computing device, that manipulate and/or transform data represented as physical, such as electronic, quantities within computing system's registers and/or memories into other data similarly represented as physical quantities within computing system's memories, registers or other such information storage, transmission or display devices.
In a similar manner, term “processor” may refer to any device or portion of a device that processes electronic data from registers and/or memory and transform that electronic data into other electronic data that may be stored in registers and/or memory. As non-limiting examples, “processor” may be a CPU or a GPU. A “computing platform” may comprise one or more processors. As used herein, “software” processes may include, for example, software and/or hardware entities that perform work over time, such as tasks, threads, and intelligent agents. Also, each process may refer to multiple processes, for carrying out instructions in sequence or in parallel, continuously or intermittently. Terms “system” and “method” are used herein interchangeably insofar as system may embody one or more methods and methods may be considered a system.
In present document, references may be made to obtaining, acquiring, receiving, or inputting analog or digital data into a subsystem, computer system, or computer-implemented machine. Obtaining, acquiring, receiving, or inputting analog and digital data can be accomplished in a variety of ways such as by receiving data as a parameter of a function call or a call to an application programming interface. In some implementations, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a serial or parallel interface. In another implementation, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a computer network from providing entity to acquiring entity. References may also be made to providing, outputting, transmitting, sending, or presenting analog or digital data. In various examples, process of providing, outputting, transmitting, sending, or presenting analog or digital data can be accomplished by transferring data as an input or output parameter of a function call, a parameter of an application programming interface or interprocess communication mechanism.
Although discussion above sets forth example implementations of described techniques, other architectures may be used to implement described functionality, and are intended to be within scope of this disclosure. Furthermore, although specific distributions of responsibilities are defined above for purposes of discussion, various functions and responsibilities might be distributed and divided in different ways, depending on circumstances.
Furthermore, although subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that subject matter claimed in appended claims is not necessarily limited to specific features or acts described. Rather, specific features and acts are disclosed as exemplary forms of implementing the claims.
