A perception-based video coding algorithm for H.264/AVC systems is proposed in this paper. Obviously, the areas containing human faces and that with larger motion activities are or most concern by human visual perception system in which more bit resources should be allocated so that better visual quality can be exhibited. To do this, those macroblocks (MBs) containing human faces are determined by...
H.264/Advanced Video Coding (AVC) is well known for its superiority of finding an optimal tradeoff between the visual quality and the bit-rate expense. Nevertheless, the highly complex procedures of finding an optimal intra- or inter-prediction mode can degrade the run-time performance of the coding process. To speed up the run-time performance during the encoding of H.264/AVC intra-prediction mode,...
