【Abstract】 A fast flexible multi-frame motion search algorithm based on H.264 was presented.The proposed algorithm reduced the computational cost by the initial search point prediction of reference frames and the hexagon search based on multi-frame.The simulation results show that the proposed algorithm can provide better competitive performance than the other search algorithms,and that the computational cost can be reduced efficiently with similar visual quality and bit rate.更多还原
