Yuan Luo, You Chihong, Yi Zhang, Tan Shaofeng · 2013
By analysis the motion estimation algorithm of the open source H.264/AVC video codec, it is showed that the number of unnecessary search point will effect the speed of the algorithms. In this paper, a novel fast hybrid temp searching algorithm based on adaptive search direction of x264 is presented. An adaptive threshold for the matching macro block is set and a series hybrid search patterns were utilized adaptively to reduce the number of unnecessary search points. Moreover, improved MRACO PIXEL_SAD_C is used to reduce the computing time of SAD. Experiment results show that the novel algorithm is effectively.
