Estimation-based intra prediction algorithm for H.264/AVC

Abstract

We propose a new intra prediction algorithm that can improve the coding efficiency of the H. 264/AVC standard. In the proposed algorithm, the prediction signal for each macroblock (MB) is formed by using all the previously reconstructed pixels of the current frame. Experimental results show that the proposed algorithm can reduce the bit rate by 1.36% to 9.07%, as compared with the conventional intra prediction, while the average PSNR is not decreased.
