Fast inter-prediction mode decision for H.264/AVC
Junjie Li · Journal of Computer Applications · 2006
A full search method used in reference software of H.264 comes at a cost of greatly increased complexity of encoder. A new scheme was proposed to optimize block mode decision and improve the efficiency of the encoder in H.264/AVC significantly. Homogeneous area, zero vector and block merging method were combined in this scheme. The experimental results of JM model show that the new scheme is able to achieve a reduction of 60% encoding time on average, with a negligible average peak signal-noise ratio (PSNR) loss(0.03dB) and bit rate increase (4%) compared with the original H.264/AVC reference software.
