Fast motion estimation algorithm in H.264 and its architecture
Guoyu Li · Information technology newsletter · 2009
This paper presents a new motion estimation algorithm for H.264 and architecture. The proposed algorithm is derived from multilevel successive elimination algorithm. Novel algorithm divides different mode block into same amount of sub-block,removes the branches to make data flow more regular and suitable for hardware to be applicable to variable block size and fractional-sample-accurate motion compensated prediction. Experiments show that the algorithm improves the search efficiency while the video quality and bit rate stays the same in most cases.
