Abstract

Block matching is a widely used method for stereo vision, visual tracking, and video compression. Among block matching motion estimation algorithms, the full search algorithm is known for its superiority in the performance over other matching techniques. However, this method is computationally very extensive. Thus, many previous fast block matching algorithms have been proposed and developed with aim to reduce computational costs while maintaining desired quality performance. One of these, which are proposed for the implementation in this project, is called Cross Search Algorithm. The aim of this algorithm is to find the optimum motion vector with minimal number of search points along the process. The performance of this algorithm will be compared to other common algorithms in terms of peak signal to noise ratio (PSNR), number of search points required and computational complexity.
