An efficient mode decision for low bit rate coding IN H.264/AVC
Yu-Ming Lee, Yinyi Lin · Internet, Multimedia Systems and Applications · 2007
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 4×4 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.
