摘要

为了进一步减少PU的RDOQ候选模式甚至跳过RDOQ，本文提出了一种HEVC快速模式内决策算法，该算法不仅利用了最优RMD模式与MPM之间的关系所反映的相邻PU的纹理一致性，而且利用了最优两个RMD模式所反映的PU的纹理特性。实验结果表明，该算法平均减少了31.3%的编码时间，BD-rate损失为0.56%。

Fast intra mode decision for HEVC based on texture characteristic from RMD and MPM

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.
