Byeongdu La, Minyoung Eom, Yoonsik Choe · International Conference on Advanced Communication Technology · 2007
We propose a novel fast sub-pixel search control algorithm for H.264 encoder by using neighbor motion vectors. This fast sub-pixel search control algorithm cuts down the motion estimation time by referring neighbor motion vectors and the current integer motion vector. This algorithm can also improve the performance of the motion estimation time more by merging other fast search algorithms with its independent discrimination.
