Research on Intra Prediction Algorithm in H.264

In this paper,a fast intra prediction algorithm for H.264 coding is introduced.The proposed algorithm uses statistical characteristic of intra mode decision and correlation of Sums of Absolute Transform Differences(SATD)and Rate Distortion(RD)performance,efficiently endues the frequency of prediction modes.Experimental results show that compared with the standard intra prediction mode of H.264,the proposed algorithm can gain 63.92% coding performance increases averagely,while the PSNR and the quality of image remain nearly unchanged.
