Abstract

To achieve high compression ratio, a method called Block Matching Motion Estimation is widely used in various coding standards. Many previous fast block matching algorithms have been proposed and developed in this method. In block matching motion estimation, search patterns with different shapes or sizes and the center-biased characteristics of motion-vector distribution have a large impact on the searching speed and quality of performance. One ofthe algorithm, which is proposed for the implementation in this project, is calJed Cross Diamond Search Algorithm. The performance of this algorithm will be compared to other common algorithms in terms of PSNR, number of search points required and computational complexity.
