One kind of mix octagon algorithm for fast motion estimation
Yuan Liu · Computer Engineering and Applications Journal · 2010
Based on the space-time correlation of video sequence motion vector and center-biased character,this paper unifies the zero movement judgment.A new kind of octagon pattern search1 is proposed.The proposed algorithm can obtain a higher precision than FS,TSS,DS,MVFAST,when the block movement is strong and due to the initial prediction to the non-static block.It also reduces the search time at the same time,and therefore enhances search speed greatly.
