The efficient motion estimation algorithms are the important research hotspot in the video coding-deco- ding technology.In order to improve the speed of motion estimation in the video coding,based on the local unimodal error surface assumption,the paper proposes a new inner predictive diamond fast motion estimation algorithm,uses inner predictive technique to speedup the original diamond search.Also it takes the advantage of the relative blocks to predict the initial point,and uses different search techniques for different motion blocks.First it eliminates static blocks,then uses SDSP search mode for the slow motion blocks,and new inner predictive DS search algorithm for the fast motion blocks.Experimental results show that the new proposed algorithm greatly improves the searching speed with negligible PSNR degradation.
