To reduce computational complexity and maintain the image quality, an integer pixel fast motion estimation algorithm is proposed in this paper. Combining the characters of the UMHexagonS algorithm and the EPZS algorithm, the proposed algorithm selects various searching patterns according to the motion types of the image and introduces a early-termination algorithm. Experimental results demonstrate that the proposed algorithm has less ME time than FS, UMHexagonS and EPZS algorithm with essentially the same PSNR.
