Title:
SAMPLE PADDING IN ADAPTIVE LOOP FILTERING
Document Type and Number:
WIPO Patent Application WO/2021/004542
Kind Code:
A1
Abstract:
A method of video processing includes determining, for a conversion between a block that is in a video picture of a video and a bitstream representation of the video, a manner of padding a first set of samples located across boundaries of multiple video regions of the video picture for a current sample in an adaptive loop filter process. The method also includes performing the conversion according to the determining.
