Zusammenfassung:A filter unit of a video encoder or video decoder can determine a first metric for a group of pixels within a block of pixels based on a comparison of a subset of the pixels in the block to other pixels in the block; determine a filter based on the first metric; and generate a filtered image by applying the filter to the group of pixels. The subset of pixels can be selected to not include pixels on the boundary of the block of pixels.
