A Study on Block Matching Algorithm with Variable-Block Size

가변 블록을 고려한 블록 정합 알고리즘에 관한 연구

A new block matching algorithm that improved the existing block matching algorithm in terms of image quality is proposed in this paper. The subblock of image including the vertical edge of object is subdivided into new two subblocks, and the moving vector found. The result of computer simulation shows on real image that the image quality by the algorithm becomes higher than that of the three step search algorithm by 1.1dB.
