Advanced block size selection algorithm for inter frame coding in H.264/MPEG-4 AVC

Abstract

A fast inter-mode selection algorithm is proposed to improve the encoder efficiency of the H.264/MPEG-4 AVC standard, but With insignificant degradation in Picture quality. The Modified Fast Inter-mode selection (MFInterms) algorithm extends previous work to provide a more efficient prediction of mode decision. The strategy incorporates temporal similarity detection and the detection of different moving features within a macroblock. Simulation results demonstrate a speed Lip in encoding time of up to 73% compared with the H.264 benchmark
