Abstract

See full text

The various implementations described herein include methods and systems for coding video. In one aspect, a method of video decoding includes receiving video data comprising a plurality of blocks, including a first block and a plurality of residual coefficients, from a video bitstream. The first block is encoded by applying a first intra prediction. The plurality of residual coefficients are generated by applying a second intra prediction to a residue block for the first block in a first direction. The residue block generated from applying the first intra prediction mode to the first block in a second direction. The method also includes generating, from the plurality of residual coefficients, a refined residue block for the first block, and reconstructing the first block using the refined residue block.
