Abstract:
1. A method of video decoding, the method comprising: obtaining, from a bitstream, information about pixel value compensation; when the information about pixel value compensation indicates one of a band type and an edge type, obtaining a plurality of offsets from the bitstream; when the information about pixel value compensation indicates the band type, applying an offset, among the plurality of offsets, to a pixel corresponding to a band among pixels of a current block; and when the information about pixel value compensation indicates the edge type, applying an offset, among the plurality of offsets, to a pixel corresponding to an edge pattern among the pixels of a current block, wherein: the band is one of a plurality of bands, the edge pattern is one of a plurality of edge patterns, when the information about pixel value compensation indicates the band type, the plurality of offsets corresponds to the plurality of bands, and when the information about pixel value compensation indicates the edge type, the plurality of offsets corresponds to the plurality of edge patterns.
