The apparatus may process at least one frame including frame content associated with a grid including a plurality of grid sections, each of a plurality of portions of the frame content being aligned with at least a portion of at least one of the plurality of grid sections. The apparatus may also shift the frame content with respect to the grid, such that at least one portion of the plurality of portions of the frame content is aligned with at least a portion of at least one distinct grid section of the plurality of grid sections. Additionally, the apparatus may store the shifted frame content including the at least one portion of the frame content that is aligned with at least a portion of the at least one distinct grid section.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. The apparatus can determine a motion estimation priority for one or more regions in a frame. In some aspects, each of the one or more regions can include a group of pixels. Additionally, the apparatus can adjust a quality of a motion estimation procedure for each group of pixels based on the motion estimation priority of the region including the group of pixels. The apparatus can also perform the motion estimation procedure for each of the at least one group of pixels to generate a motion vector for the at least one group of pixels based on the adjusted quality of the motion estimation procedure.

Abstract: Example techniques are described for generating graphics content by obtaining a rendering command for a frame of the graphics content, obtaining an eye position of a user after obtaining the rendering command, determining a foveation parameter for a region of the graphics content based on the eye position; and rendering a tile, of the frame, corresponding to the region of the graphics content using the foveation parameter and the rendering command.

Abstract: Example techniques are described for generating graphics content by assigning a first region of the graphics content to a first tile, assigning a second region of the graphics content to a second tile, determining, at the first tile and at a first resolution, a first set of samples of the graphics content for each pixel of multiple pixels associated with the first region, determining, at the second tile and at a second resolution that is lower than the first resolution, a second set of samples of the graphics content for each pixel of multiple pixels associated with the second region, downsampling the first set of samples into a combined set of samples, preserving samples of the second set of samples to generate a third set of samples with preserved samples, storing the combined set of samples, and storing the third set of samples with preserved samples.

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.

Abstract: The present disclosure relates to methods and devices for image or frame processing including an apparatus, e.g., a GPU. In some aspects, the apparatus may identify a discontinuity between at least one first region of a first frame and at least one second region of a second frame, the at least one first region corresponding to the at least one second region. The apparatus may also determine whether the discontinuity between the at least one first region and the at least one second region is greater than or equal to a motion estimation threshold. The apparatus may also skip a motion estimation for the at least one first region and the at least one second region when the discontinuity between the at least one first region and the at least one second region is greater than or equal to the motion estimation threshold.

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 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: 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.
