Abstract: In various examples, object fence corresponding to objects detected by an ego-vehicle may be used to determine overlap of the object fences with lanes on a driving surface. A lane mask may be generated corresponding to the lanes on the driving surface, and the object fences may be compared to the lanes of the lane mask to determine the overlap. Where an object fence is located in more than one lane, a boundary scoring approach may be used to determine a ratio of overlap of the boundary fence, and thus the object, with each of the lanes. The overlap with one or more lanes for each object may be used to determine lane assignments for the objects, and the lane assignments may be used by the ego-vehicle to determine a path or trajectory along the driving surface.

Abstract: Methods for generating a partial three-dimensional representation of a person are disclosed herein. In one aspect, a computer-implemented method comprises obtaining depth data of the person captured from a stationary depth camera scanning around the person; segmenting the depth data into a first segment; mapping the depth data of the first segment to a plurality of point clouds; performing pairwise registration on the point clouds of the first segment; segmenting the depth data into a second segment; mapping the depth data of the second segment to a plurality of point clouds; performing pairwise registration on the point clouds of the second segment; and merging the registered point clouds of the first and second segments to generate the partial 3D representation of the person.

Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU or CPU. The apparatus may allocate each of a plurality of primitives in a scene into one of a plurality of bounding boxes, each of the plurality of bounding boxes corresponding to a plurality of nodes including internal nodes and leaf nodes. The apparatus may also identify whether each of the plurality of nodes is one of the internal nodes or one of the leaf nodes. Further, the apparatus may estimate a compressibility of each of the plurality of nodes if the node is one of the leaf nodes, the compressibility of the node corresponding to whether the node is compressible. The apparatus may also compress data corresponding to each of the plurality of nodes if the node is estimated to be compressible.

Abstract: Systems, methods, and non-transitory computer-readable media can identify a virtual character being presented to a user within a real-time immersive environment. A first animation to be applied to the virtual character is determined. A nonverbal communication animation to be applied to the virtual character simultaneously with the first animation is determined. The virtual character is animated in real-time based on the first animation and the nonverbal communication animation.

Abstract: Enhanced techniques applicable to a ray tracing hardware accelerator for traversing a hierarchical acceleration structure are disclosed. The traversal efficiency of such hardware accelerators are improved, for example, by transforming a ray, in hardware, from the ray's coordinate space to two or more coordinate spaces at respective points in traversing the hierarchical acceleration structure. In one example, the hardware accelerator is configured to transform a ray, received from a processor, from the world space to at least one alternate world space and then to an object space in hardware before a corresponding ray-primitive intersection results are returned to the processor. The techniques disclosed herein facilitate the use of additional coordinate spaces to orient acceleration structures in a manner that more efficiently approximate the space occupied by the underlying primitives being ray-traced.

Abstract: he The target includes a plurality of keypoints of a body including a plurality of joints and the 3D position of the target is identified by positions of the plurality of keypoints. A bounding box and reference 2D joint position determining unit determines a bounding box surrounding the target in a camera image at a target frame to be predicted subsequent to at least one frame at which imaging is performed by the plurality of cameras using the 3D positions of the keypoints of the target at the at least one frame and acquires reference 2D positions of the keypoints projected from the 3D positions of the keypoints of the target onto a predetermined plane. A 3D pose acquiring unit acquires the 3D positions of the keypoints of the target at the target frame using image information in the bounding box and the reference 2D positions.
