AVS的SKIP和帧内模式快速选择的研究

Research on fast selection of SKIP and intra mode for AVS

AVS是我国拥有自主知识产权的数字音视频编码技术标准.AVS利用RDO进行模式的选择,计算所有模式的RDO,所需计算量庞大.本文提出一种提前判决SKIP模式和有选择的帧内预测的算法,可以有效减少模式数量.仿真结果表明,该方法保持原有的视频质量和比特率略有上升的情况下,能有效减少时间.

AVS is a set of domestic Audio Video-coding Standard series standards. AVS makes use of RDO technique in mode decision,but calculations of all modes of RDO increase computational complexity. In order to reduce model number, the paper proposes a SKIP mode decision algorithm and selective intra mode decision. Results show that the algorithm can shorten the encoding time while maintaining similar video quality and increasing a little code rate.
