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 up in encoding time of up to 73% compared with the H.264 benchmark.
