摘要：Multiple reference pictures and variable prediction block sizes in motion estimation/compensation (ME/MC) adopted in video coding standards such as H.264/AVC and H.265/HEVC achieve high coding efficiency, but these tools require heavy encoding complexity. This paper introduces a reference picture selection method based on the spatial correlation between neighboring coded blocks and the temporal correlation between the reference pictures of a reference picture list. This method can reduce the number of reference picture to be searched in ME process. This reduction provides competitive performance with reduced computational complexity. Experimental results show that the proposed method reduces encoding run-time by 47%, with a negligible degradation of coding efficiency.
