Abstract :
A motion estimation algorithm which exploits the motion correlation of neighbor blocks in temporal and spatial directions is presented. Compared to existing fast block matching algorithms, this algorithm achieves significant savings of computation time and the amount of side information of motion vectors. In addition, better estimation accuracy is also obtained
