Diamond Search(DS) algorithm is a better one among the so many fast block match motion estimation algorithms.By analyzing the characteristic of DS,it is found that DS can be improved too.A Modified Diamond Search(MDS) algorithm is proposed in this paper to overcome the defect of DS.Experimental results show that MDS can speed up the motion estimation process greatly under the same encoding efficiency compared to DS,especially for those video sequences with simple and slow motion vectors.
