Abstract

H.264/AVC is the newest video coding standard jointly developed by the ITU-T Video Coding Experts Group and the ISO/ISE Moving Picture Expert Group. Compared to previous standards, aggressive compression techniques such as intra prediction, adaptive block size motion compensation, and 4x4 block based prediction are employed in this standard. As a result, this standard greatly outperforms other standards with significant bit-rate reduction. In this paper, we present a new intra-prediction algorithm for the H.264/AVC standard. The proposed algorithm generates additional prediction blocks by using previously reconstructed blocks in order to reduce the amount of bits for video representation. Experimental results show that the proposed algorithm is superior to conventional methods in terms of compression ratio.
