Fast intra mode decision for HEVC based on texture characteristic from RMD and MPM
Dongdong Zhang, Youwei Chen, Ebroul Izquierdo · 2014
In this paper, we proposed a fast intra mode decision algorithm for HEVC to further reduce the candidate modes of RDOQ or even skip RDOQ for a PU, which exploited not only the texture consistency of neighbouring PUs reflected by the relation between the optimal RMD mode and MPM, but also the texture characteristic in a PU reflected by the best two RMD modes. Experimental results show that our proposed algorithm can reduce 31.3% intra coding time with 0.56% BD-rate loss on average.
