Abstract

The computational complexity of H.264/AVC is dramatically increased due to variable block-size modes performed. In this paper, a fast intermode decision algorithm, based on the number of zero blocks of 4x4 DCT coefficients between the current macroblock and the collocated macroblock, is proposed to reduce the computation time. Experimental results show that the proposed method significantly outperforms other mode decision algorithms investigated in computation for low bit rate coding.
