Intra prediction method for reducing prediction mode information
Ming Li · Journal of Xidian University · 2010
A new intra prediction method is proposed for H.264/AVC intra frame coding.The sum of absolute differences(SAD) between each predicted block and the DC predicted block is used to determine whether those predicted blocks are similar.The average of those predicted blocks is used as the final predicted result if the predicted blocks are similar,and it is useless to encode the prediction mode.Experimental results demonstrate that compared with H.264/AVC,the bit rate can be reduced 2.40% on average,while the PSNRs of reconstructed videos are the same.At the same time,the encoding time is reduced by 25.83% on average.
