【Abstract】This paper proposes a novel fast multi-frame motion estimation algorithm based on H.264. The proposed algorithm can reduce the computational complexity by predic the initial search point prediction of the reference frames and extending the diamond search to multiple reference frames. Experimental results show that the algorithm can decrease the encoding time by 60% while maintaining nearly unchanged PSNR of pictures and bit rate compared to the fast motion estimation algorithm named UMHexagonS in H.264 reference software JM9.6. 【Key words】multi-frame; motion estimation; initial search point; diamond search
