Abstract

This application is directed to processing video data that includes a plurality of luma samples and a plurality of chroma samples corresponding to a plurality of pixel groups of a video frame. For each pixel group, an electronic device identifies a respective chroma sample and a set of luma samples and determines an anchor luma sample from the set of luma samples. A chroma refinement value is generated based on the set of luma samples by differencing a respective luminance value of each luma sample in the set by an anchor luminance value of the anchor luma sample and applying a cross component filter to the difference luminance values of the set of luma samples. The electronic device then updates the chroma sample using the chroma refinement value for each pixel group and stores the updated respective chroma sample of each pixel group in association with the video frame.
