SYSTEMS AND METHODS FOR ENTROPY CODING FOR RECURSIVE INTRA REGION PARTITIONING

Abstract: an example method of video coding includes receiving a video bitstream including a plurality of coding blocks; identifying a coding region that includes two or more coding blocks of the plurality of coding blocks that are encoded in a first prediction mode. the method also includes entropy decoding a signaled flag indicating a prediction mode for the coding region, the entropy decoding using coded information including one or more of: previous instances of the signaled flag, a block size of a current coding block, a block size group of the current coding block, respective block sizes of a set of neighboring coding blocks, respective block size groups of the set of neighboring coding blocks, and signaled flags for the set of neighboring coding blocks; and reconstructing the two or more coding blocks according to a value of the signaled flag for the coding region.
