Fast intra skip method in H.264/AVC by using fuzzy logic

Abstract

In inter-frame coding of H.264/AVC standard, there are inter partition modes and intra modes to be taken into account for seeking best mode. Although it can achieve higher coding efficiency than any other previous coding standard, the computation complexity also increases significantly. In this work, based on the information of the histogram differences and rate part of rate-distortion optimization, fuzzy reasoning technique is used to determine the intra skip in inter-frame coding to decrease the encoding time. Experimental results show that the encoding time is reduced up to 32%, and the quality is almost remained and bit-rate is slightly increased.
