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.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for efficient local normalization for DFS. A processor may determine a target granularity based on at least one of a first image buffer or a second image buffer. The processor may determine a partial image pyramid based on the target granularity and at least one of the first image buffer or the second image buffer. The processor may sample the partial image pyramid based on the target granularity. The processor may determine a midpoint normalization value based on the sampled partial image pyramid. The processor may normalize at least one of the first image buffer or the second image buffer based on the midpoint normalization value.

Abstract: Aspects presented herein relate to methods and devices for display processing including an apparatus, e.g., a DPU. The apparatus may obtain an indication of associated with a plurality of pixels corresponding to a plurality of color channels. The apparatus may also divide each of the plurality of color channels. The apparatus may also select at least one first color channel of the plurality of divided color channels. Further, the apparatus may scale each of the pixels associated with the at least one first color channel. The apparatus may also blend, based on each of the plurality of scaled pixels, all of the plurality of pixels associated with the at least one first color channel. The apparatus may also transmit, based on all of the plurality of blended pixels, an indication of the plurality of pixels associated with the at least one first color channel.

Abstract: Systems and techniques are provided for synchronizing a frame rate of pass-through content from a camera and a display refresh rate. An example method can include obtaining first and second frames captured by an image capture device (which may be part of a device, such as an extended reality (XR) device). A display refresh rate of a display is greater than a camera frame rate of the image capture device. The method may determine motion between the first frame and the second frame. The method can include predicting, based on the second frame and the determined motion, a third frame corresponding to a time after the second frame. The method can include displaying content (e.g., mixed reality content) including the predicted third frame and virtual content rendered for the XR device.

Abstract: A frame processor may generate a mask based on one or more static regions of a first set of frames of a plurality of previous frame and adjust the mask to at least one of determine alpha data or conceal distorted content associated with the one or more static regions of the first set of frames. The distorted content may be caused by extrapolation of a frame from a second set of frames of the plurality of previous frames. The frame processor may generate a composite frame based on application of at least one of the mask or the alpha data to a previous frame of the plurality of frames, and application of the previous frame based on the at least one of the mask or the alpha data to the frame extrapolated from the second set of frames of the plurality of previous frames.
