Inter-Block Dependencies Consideration Applied to Intra Coding in H.264/AVC and HEVC standards

Abstract: 

Recent MPEG video compression standards are still block-based: blocks of pixels are sequentially coded using spatial or temporal prediction schemes. For each block, a vector of coding parameters has to be selected. In order to limit the complexity of this decision, independence between blocks is assumed, and coding parameters are locally optimized to maximize the coding efficiency. Few studies have investigated the benefits of inter-block dependencies consideration using Joint Rate-Distortion Optimization (JRDO), especially in Intra coding. To the best of our knowledge, maximum achievable gains of such approaches have never been exhibited. In this paper, we propose two JRDO models performing joint optimization of multiple blocks applied to intra prediction mode decision. The proposed models have been evaluated in both H.264/AVC and HEVC standards. These two models enables a bitrate saving with respect to the classical RDO model up to -3.10% and -2.31% in H.264/AVC and HEVC, respectively.
