A Fast Block Motion Estimation Algorithm Based On Motion Classification And Directional Search Patterns

움직임 분류와 직접 탐색 패턴을 통한 고속 블록 움직임 추정 알고리즘

This paper suggests a simple scheme of block motion estimation in which the search pattern selection is based on the classification of motion content available in the spatio temporal neighboring blocks. The search area is divided into eight sectors and the search pattern selection is also based on the direction of predicted motion vector. Experimental results show that the proposed algorithm has achieved good predicted image quality measured in terms of PSNR and has very less computational complexity.
