Adaptive coding mode decision algorithm for H.264
Qing Chang · Optical Technique · 2006
In order to reduce the encoding complexity of macroblock coding mode decision in H.264/AVC,.a selective smaller block-size searching algorithm and a selective intra-coding modes searching algorithm are proposed by using the high correlation between coding modes and in spatial and temporal domains of video sequence.Simulation results demonstrate that the proposed algorithm can provide significant improvement in computational requirement,with negligible small picture quality degradation and slight bit rate increase.
