IMAGE SYNTHESIS USING DIFFUSION MODELS CREATED FROM SINGLE OR MULTIPLE VIEW IMAGES
A method and system for performing novel image synthesis using generative networks are provided. The encoder-based model is trained to infer a 3D representation of an input image. A feature image is then generated using volume rendering techniques in accordance with the 3D representation. The feature image is then concatenated with a noisy image and processed by a denoiser network to predict an output image from a novel viewpoint that is consistent with the input image. The denoiser network can be a modified Noise Conditional Score Network (NCSN). In some embodiments, multiple input images or keyframes can be provided as input, and a different 3D representation is generated for each input image. The feature image is then generated, during volume rendering, by sampling each of the 3D representations and applying a mean-pooling operation to generate an aggregate feature image.

IMAGE STITCHING WITH SACCADE-BASED CONTROL OF DYNAMIC SEAM PLACEMENT FOR SURROUND VIEW VISUALIZATION
In various examples, a stitched image may be generated from overlapping image frames using a dynamic seam placement that depends on scene content and/or other factors. Since an optimized seam placement may jump from a previous location from time slice to time slice, one or more constraints may be applied to limit the movement of dynamically placed seams such that any given seam moves gradually over time, limiting potential discontinuities in a visualization of the stitched image on a display. Eye tracking may be used to detect a saccade of a monitored person and/or detect that the monitored person is not looking at the display, and one or more of the constraints used to limit the movement of dynamically placed seams may be relaxed or lifted when the monitored person is experiencing a saccade and/or is looking away from the display.

Systems and methods are disclosed for improving natural robustness of sparse neural networks. Pruning a dense neural network may improve inference speed and reduces the memory footprint and energy consumption of the resulting sparse neural network while maintaining a desired level of accuracy. In real-world scenarios in which sparse neural networks deployed in autonomous vehicles perform tasks such as object detection and classification for acquired inputs (images), the neural networks need to be robust to new environments, weather conditions, camera effects, etc. Applying sharpness-aware minimization (SAM) optimization during training of the sparse neural network improves performance for out of distribution (OOD) images compared with using conventional stochastic gradient descent (SGD) optimization. SAM optimizes a neural network to find a flat minimum: a region that both has a small loss value, but that also lies within a region of low loss.

In order to reduce the size, computation, and latency of a neural network model, a compression technique can be employed which includes model sparsification. To avoid the negative consequences of pruning a fully pretrained neural network model and on the other hand of training a sparse model in the first place without any recovery option, the present disclosure provides a dynamic neural network model sparsification process which allows for recovery of previously pruned parts to improve the quality of the sparse neural network model.
Approaches presented herein provide systems and methods for determining duplicate objects within an interaction environment.

Copies of duplicate or near-duplicate objects may then be deleted from the interaction environment and represented by a common object to which one or more additional transforms are applied.

A remote device utilizes ray tracing to compute a light field for a scene to be rendered, where the light field includes information about light reflected off surfaces within the scene. This light field is then compressed utilizing one or more video compression techniques that implement temporal reuse, such that only differences between the light field for the scene and a light field for a previous scene are compressed.

This light field is then used by the client device to compute global illumination for the scene. The global illumination may be used to accurately render the scene at the mobile device, resulting in a realistic scene that is presented by the mobile device.

GENERATIVE MACHINE LEARNING MODELS FOR PRIVACY PRESERVING SYNTHETIC DATA GENERATION USING DIFFUSION
In various examples, systems and methods are disclosed relating to differentially private generative machine learning models. Systems and methods are disclosed for configuring generative models using privacy criteria, such as differential privacy criteria. The systems and methods can generate outputs representing content using machine learning models, such as diffusion models, that are determined in ways that satisfy differential privacy criteria. The machine learning models can be determined by diffusing the same training data to multiple noise levels.
Denoising images rendered using Monte Carlo sampled ray tracing is an important technique for improving the image quality when low sample counts are used. Ray traced scenes that include volumes in addition to surface geometry are more complex, and noisy when low sample counts are used to render in real-time. Joint neural denoising of surfaces and volumes enables combined volume and surface denoising in real time from low sample count renderings. At least one rendered image is decomposed into volume and surface layers, leveraging spatio-temporal neural denoisers for both the surface and volume components. The individual denoised surface and volume components are composited using learned weights and denoised transmittance. A surface and volume denoiser architecture outperforms current denoisers in scenes containing both surfaces and volumes, and produces temporally stable results at interactive rates.
Various embodiments include techniques for lock-free, unordered in-place compaction of an array. The techniques include receiving a first array that includes a first plurality of data entries, generating a second array that includes a second plurality of data entries, and storing, in the second array, respective index positions of valid data entries included in the first array and invalid data entries included in the first array. The techniques further include determining invalid data entries included in a first portion of the first array based at least on the index positions, determining valid data entries included in a second portion of the first array based at least on the index positions, and replacing contents of the invalid data entries included in the first portion of the first array with contents of the valid data entries included in the second portion of the first array.
In various examples, a two-dimensional (2D) and three-dimensional (3D) deep neural network (DNN) is implemented to fuse 2D and 3D object detection results for classifying objects. For example, regions of interest (ROIs) and/or bounding shapes corresponding thereto may be determined using one or more region proposal networks (RPNs)—such as an image-based RPN and/or a depth-based RPN. Each ROI may be extended into a frustum in 3D world-space, and a point cloud may be filtered to include only points from within the frustum. The remaining points may be voxelated to generate a volume in 3D world space, and the volume may be applied to a 3D DNN to generate one or more vectors. The one or more vectors, in addition to one or more additional vectors generated using a 2D DNN processing image data, may be applied to a classifier network to generate a classification for an object.

Systems and methods relate to facial video encoding and reconstruction, particularly in ultra-low bandwidth settings. In embodiments, a video conferencing or other streaming application uses automatically tracked feature cropping information. A bounding shape size—used to identify the cropped region—varies and is dynamically determined to maintain a proportion for feature reconstruction, such as resizing in the event of a zoom-in on a face (or other feature of interest) or a zoom-out. The tracking scheme may be used to smooth sudden movements, including lateral ones, to generate more natural transitions between frames. Tracking and cropping information (e.g., size and position of the cropped region) may be embedded within an encoded bitstream as supplemental enhancement information (“SEI”), for eventual decoding by a receiver and for compositing a decoded face at a proper location in the applicable stream.

In various examples, color statistic(s) from ground projections are used to harmonize color between reference and target frames representing an environment. The reference and target frames may be projected onto a representation of the ground (e.g., a ground plane) of the environment, an overlapping region between the projections may be identified, and the portion of each projection that lands in the overlapping region may be taken as a corresponding ground projection. Color statistics (e.g., mean, variance, standard deviation, kurtosis, skew, correlation(s) between color channels) may be computed from the ground projections (or a portion thereof, such as a majority cluster) and used to modify the colors of the target frame to have updated color statistics that match those from the ground projection of the reference frame, thereby harmonizing color across the reference and target frames.

IMAGE STITCHING WITH COLOR HARMONIZATION OF DE-PROCESSED IMAGES FOR SURROUND VIEW SYSTEMS AND APPLICATIONS
In various examples, color harmonization is applied to images of an environment in a reference light space. For example, different cameras on an ego-object may use independent capturing algorithms to generate processed images of the environment representing a common time slice using different capture configuration parameters. The processed images may be transformed into deprocessed images by inverting one or more stages of image processing to transform the processed images into a reference light space of linear light, and color harmonization may be applied to the deprocessed images in the reference light space. After applying color harmonization, corresponding image processing may be reapplied to the harmonized images using corresponding capture configuration parameters, the resulting processed harmonized images may be stitched into a stitched image, and a visualization of the stitched image may be presented (e.g., on a monitor visible to an occupant or operator of the ego-object).
Systems and methods provide for a machine learning system to train a machine learning model to output a multi-frame blank symbol when processing an auditory input. For example, as the system generates paths through a probability lattice, one or more paths include a multi-frame blank that skips at least one frame associated with the probability lattice. The inclusion of the multi-frame blank symbol may increase a total number of potential paths through the probability lattice, and may allow the machine learning model to more quickly and accurately process audio frames, while disregarding audio frames of less value. In deployment, when an output of the machine learning model indicates a multi-frame blank symbol or token, one or more frames of the auditory input may be omitted from processing.
Various embodiments include a memory device that is capable of performing write training operations. Prior approaches for write training involve storing a long data pattern into the memory followed by reading the long data pattern to determine whether the data was written to memory correctly. Instead, the disclosed memory device stores a first data pattern (e.g., in a FIFO memory within the memory device) or generates the first data pattern (e.g., using PRBS) that is compared with a second data pattern being transmitted to the memory device by an external memory controller. If data patterns match, then the memory device stores a pass status in a register, otherwise a fail status is stored in the register. The memory controller reads the register to determine whether the write training passed or failed.
In various examples, a deep neural network (DNN) may be used to detect and classify animate objects and/or parts of an environment. The DNN may be trained using camera-to-LiDAR cross injection to generate reliable ground truth data for LiDAR range images. For example, annotations generated in the image domain may be propagated to the LiDAR domain to increase the accuracy of the ground truth data in the LiDAR domain—e.g., without requiring manual annotation in the LiDAR domain. Once trained, the DNN may output instance segmentation masks, class segmentation masks, and/or bounding shape proposals corresponding to two-dimensional (2D) LiDAR range images, and the outputs may be fused together to project the outputs into three-dimensional (3D) LiDAR point clouds. This 2D and/or 3D information output by the DNN may be provided to an autonomous vehicle drive stack to enable safe planning and control of the autonomous vehicle.

NEURAL NETWORK ACCELERATOR USING LOGARITHMIC-BASED ARITHMETIC
Neural networks, in many cases, include convolution layers that are configured to perform many convolution operations that require multiplication and addition operations. Compared with performing multiplication on integer, fixed-point, or floating-point format values, performing multiplication on logarithmic format values is straightforward and energy efficient as the exponents are simply added. However, performing addition on logarithmic format values is more complex. Conventionally, addition is performed by converting the logarithmic format values to integers, computing the sum, and then converting the sum back into the logarithmic format. Instead, logarithmic format values may be added by decomposing the exponents into separate quotient and remainder components, sorting the quotient components based on the remainder components, summing the sorted quotient components to produce partial sums, and multiplying the partial sums by the remainder components to produce a sum. The sum may then be converted back into the logarithmic format.

Various embodiments include techniques for generating topological data for a mesh included in a computer-generated environment. The mesh includes simple geometric shapes, such as triangles. The disclosed techniques identify vertices in the mesh that have the same position and have identical attributes, such as color, normal vector, and texture coordinates. The disclosed techniques further identify vertices in the mesh that have the same position but differ in one or more attributes. The techniques generate lists of the triangles that are adjacent to each vertex included in the mesh. The techniques generate a list of the unique edges included in the mesh. Further, the techniques are well suited for execution on highly parallel processors, such as graphics processing units, thereby reducing the time to generate this topological data. The topological data may then be efficiently used by other computer graphics processing operations.
Techniques are disclosed for improving the throughput of ray intersection or visibility queries performed by a ray tracing hardware accelerator. Throughput is improved, for example, by releasing allocated resources before ray visibility query results are reported by the hardware accelerator. The allocated resources are released when the ray visibility query results can be stored in a compressed format outside of the allocated resources. When reporting the ray visibility query results, the results are reconstructed based on the results stored in the compressed format. The compressed format storage can be used for ray visibility queries that return no intersections or terminate on any hit ray visibility query. One or more individual components of allocated resources can also be independently deallocated based on the type of data to be returned and/or results of the ray visibility query.
In various examples, live perception from sensors of a vehicle may be leveraged to detect and classify intersections in an environment of a vehicle in real-time or near real-time. For example, a deep neural network (DNN) may be trained to compute various outputs—such as bounding box coordinates for intersections, intersection coverage maps corresponding to the bounding boxes, intersection attributes, distances to intersections, and/or distance coverage maps associated with the intersections. The outputs may be decoded and/or post-processed to determine final locations of, distances to, and/or attributes of the detected intersections.

The GUI dashboard is generated with unit cells organized by the subset of network address identifiers as rows, time intervals as columns, colors as a configurable anomaly score indicator, and a number of network access events as column heights. Each unit cell is a colored, 3D visual object representing a composite score of anomaly scores associated with zero or more network access events corresponding to the respective network address identifier at the respective time interval. The GUI dashboard is rendered on a display.

One embodiment of a method for generating representations of scenes includes assigning each image included in a set of images of a scene to one or more clusters of images based on a camera pose associated with the image, and performing one or more operations to generate, for each cluster included in the one or more clusters, a corresponding three-dimensional (3D) representation of the scene based on one or more images assigned to the cluster.
Systems techniques to control a robot are described herein. In at least one embodiment, a machine learning model for controlling a robot is trained based at least on one or more population-based training operations or one or more reinforcement learning operations.

Various embodiments include techniques for performing parallel edge decimation on a high resolution mesh by collapsing multiple edges in parallel by blocking only the neighbor edges of the edges selected as collapse candidates. Effectively, the disclosed techniques dynamically partition the mesh into small partitions around the collapse candidates. In this manner, the techniques identify all the edges that may be independently collapsed in a single, now parallel, iteration. Edge decimation may be performed so that certain computational geometry techniques can be efficiently applied to a simpler mesh. In so doing, the disclosed techniques preserve the history of how the edge decimation process displaces the vertices of the original mesh to generate the simplified mesh. As a result, the results of the computational geometry techniques as applied to the simplified mesh can be propagated back to the original mesh.
A method for generating, by an encoder-based model, a three-dimensional (3D) representation of a two-dimensional (2D) image is provided. The encoder-based model is trained to infer the 3D representation using a synthetic training data set generated by a pre-trained model. The pre-trained model is a 3D generative model that produces a 3D representation and a corresponding 2D rendering, which can be used to train a separate encoder-based model for downstream tasks like estimating a triplane representation, neural radiance field, mesh, depth map, 3D key points, or the like, given a single input image, using the pseudo ground truth 3D synthetic training data set. In a particular embodiment, the encoder-based model is trained to predict a triplane representation of the input image, which can then be rendered by a volume renderer according to pose information to generate an output image of the 3D scene from the corresponding viewpoint.

SENSOR CALIBRATION USING FIDUCIAL MARKERS FOR IN-CABIN MONITORING SYSTEMS AND APPLICATIONS
In various examples, sensor parameter calibration techniques for in-cabin monitoring systems and applications are presented. An occupant monitoring system (OMS) is an example of a system that may be used within a vehicle or machine cabin to perform real-time assessments of driver and occupant presence, gaze, alertness, and/or other conditions. In some embodiments, a calibration parameter for an interior image sensor is determined so that the coordinates of features detected in 2D captured images may be referenced to an in-cabin 3D coordinate system. In some embodiments, a processing unit may detect fiducial points using an image of an interior space captured by a sensor, determine a 2D image coordinate for a fiducial point using the image, determine a 3D coordinate for the fiducial point, determine a calibration parameter comprising a rotation-translation transform from the 2D image coordinate and the 3D coordinate, and configure an operation based on the calibration parameter.

MULTI-MODAL SENSOR CALIBRATION FOR IN-CABIN MONITORING SYSTEMS AND APPLICATIONS
In various examples, calibration techniques for interior depth sensors and image sensors for in-cabin monitoring systems and applications are provided. An intermediary coordinate system may be generated using calibration targets distributed within an interior space to reference 3D positions of features detected by both depth-perception and optical image sensors. Rotation-translation transforms may be determined to compute a first transform (H1) between the depth-perception sensor's 3D coordinate system and the 3D intermediary coordinate system, and a second transform (H2) between the optical image sensor's 2D coordinate system and the intermediary coordinate system. A third transform (H3) between the depth-perception sensor's 3D coordinate system and the optical image sensor's 2D coordinate system can be computed as a function of H1 and H2. The calibration targets may comprise a structural substrate that includes one or more fiducial point markers and one or more motion targets.

A receiver device includes detection logic, error counter logic, and threshold logic. The detection detects frame errors in data frames received by a transmitter device. The error counter logic increments a first value of an error count responsive to each error signal, indicative of a frame error in a data frame, received from the detection logic. The error counter logic reduces the first value to a second value (non-zero value) for the error count responsive to receiving a decrement signal and a period marker signal corresponding to a programmable period. The error counter logic resets the first value or the second value of the error count to zero responsive to receiving a reset signal. The threshold logic compares a current value of the error count with a threshold number of frame errors and output an interrupt responsive to the current value satisfying the threshold number of frame errors.
Systems and methods for cooling a datacenter(100) are disclosed. One or more circuits of a datacenter(100) cooling system can receive a speed control signal for a pulse width modulation (PWM) fan and can modify a speed control signal to output a direction control signal to a motor driver associated with a PWM fan, so that a direction control signal can enable a forward direction or a reverse direction for a PWM fan, while a speed control signal can enable a speed of a PWM fan.
