Abstract: The present disclosure relates to methods and devices for motion estimation which may include a GPU. In one aspect, the GPU may generate at least one first motion vector in a first subset of a frame, the first motion vector providing a first motion estimation for image data in the first subset of the frame. The GPU may also perturb the image data. Also, the GPU may generate at least one second motion vector based on the perturbed image data, the second motion vector providing a second motion estimation for the image data. Moreover, the GPU may compare the first motion vector and the second motion vector. Further, the GPU may determine at least one third motion vector for the motion estimation of the image data based on the comparison between the first motion vector and the second motion vector.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for mesh stitching for motion estimation and depth from stereo. A processor may obtain an indication of a mesh associated with a set of motion vectors for a first frame and a second frame in a plurality of frames. The processor may detect a set of regions in the mesh including a set of motion disparity values associated with the set of motion vectors, where each motion disparity value in the set of motion disparity values is less than a coherency threshold. The processor may calculate an adjustment to the mesh based on the region. The processor may output an indication of the adjustment to the mesh.

Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a graphics processing unit (GPU). The apparatus may obtain a first indication of a first image including a set of first image sections with a plurality of first subsections and a second indication of a second image including a set of second image sections with a plurality of second subsections. The apparatus may also compare one first image section with one second image section. Further, the apparatus may calculate a magnitude of difference between one first subsection and each of the multiple second subsections. The apparatus may also output a third indication of at least one of: (1) a lowest magnitude of difference between the one first subsection and each of the multiple second subsections or (2) a set of coordinates for a second subsection that corresponds to the lowest magnitude of difference.

Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU or a DPU. The apparatus may obtain at least one image in a set of images corresponding to a scene associated with the graphics processing. The apparatus may also perform a non-linear foveated compression process on the at least one image, where the non-linear foveated compression process corresponds to a continuous non-linear compression for a portion of the at least one image. The apparatus may also transmit the at least one image after the non-linear foveated compression process, such that the transmitted at least one image corresponds to at least one compressed image.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. The apparatus can determine whether motion estimation for image data in a frame is greater than or equal to a motion estimation threshold. A plurality of motion vectors in the frame can provide the motion estimation, where the motion vectors can include a first motion vector and a second motion vector. Further, the apparatus can compare the first motion vector and the second motion vector when the motion estimation is greater than or equal to the motion estimation threshold, where the first motion vector includes a first motion value and the second motion vector includes a second motion value. Additionally, the apparatus can determine whether a difference between the first motion value and the second motion value is greater than or equal to a motion value threshold. The apparatus can also save resources by rendering visible sub-primitives.
