H.264/AVC emploies RDO technique in inter-frame mode selection to enhance coding efficiency,but it increases computational complexity drastically.The proposed fast algorithm exploits rate distortion characteristic and spatio-temporal correlation among neighboring macroblocks to reduce the range of candidate modes,which can efficiently save the inter prediction complexity.Experimental results show that the approach reduces the coding time by 25%~46% with similar visual quality and bit rate of H.264/AVC.
