A new search method for block motion estimation in video compression

One of the most significant part of any video coding standard is Motion estimation. The purpose of this paper is to review recent research on the search techniques for block motion estimation, and to present a new search method for the same which uses its neighboring blocks for the prediction of motion vectors. This method uses the motion vectors of neighboring blocks which are more likely to be helpful in the prediction process. A search center is located, with the help of these motion vectors, a search window is placed around it. In this paper, we have proposed sorted method algorithm by forming a combination of current block with different neighborhood blocks, and compared the result.
