H.264/AVC enhances the coding efficiency and image quality at the cost of a high computational complexity.By analyzing the Coded Block Pattern(CBP) and the correlation of neighboring modes,a fast inter mode selection algorithm is proposed.The information contained in CBP and the correlations of neighboring modes are analyzed to gain the mode classification that the optimization mode belongs to,thus decreases the number of mode need to be calculated.Experimental results show that the coding time reduces about 58% without obvious PSNR and bitrate change.
