Fast Intra-Mode Decision in H.264 using Interblock Correlation

In this paper, a fast intra mode decision algorithm for H.264 that exploits the interblock correlation in the intra-mode domain is proposed to reduce computational complexity. Four modes of neighboring coded macroblocks/blocks are considered as the good candidate intra modes of the current block. Experimental results show that the proposed method can efficiently save the computation cost with little degradation in the rate-distortion performance.
