Abstract	In this paper, an efficient search center definition algorithm is proposed for H.264/AVC. H.264/AVC achieved high coding efficiency by introducing some new coding tools including a new definition of the search center. However, the definition of the search center is not efficient in the case of significant motions. This work proposes some new search center candidates using spatial and temporal correlations of motion vectors to improve the coding efficiency. Simulation results show that the proposed search centers can achieve very much bit saving but induced high computation complexity. Additional complexity reduction algorithm is also introduced to improve the trade off between bit saving and implementation performance. This work realized a maximum bit saving of 19%.
