Fast SKIP and intra mode decision algorithm in H.264

The H.264/AVC standard employs several powerful coding methods to obtain a high compression efficiency.Due to the large number of combinations of coding modes,the mode decision process requires an extremely large number of computations.To reduce the complexity,a low complexity algorithm was developed which combines fast SKIP mode prediction and selective intra mode decisions.Simulations show that the methods reduce the encoding time by 16.4% with only negligible loss in coding efficiency(0.05 dB decrease in PSNR and 0.72% decrease in bit-rate).This algorithm can be easily incorporated into a wide variety of fast mode selection algorithms.
