Abstract

In this paper, we proposed that technique for reducing trailing artifact in MPEG-4 video. low bit-rate video is occured trailng artifact which remain part of moving object. Because MEMC doesn't work well in the degraded video. The proposed trailing artifact reduction approach has at its core three main steps. First step is to detect trailing artifact. Second step is applied intra block coding to remove trailing artifact. Finally, bit-rate control algorithm is used. Experimental result using an MPEG-4 based encoder indicate that the proposed method has overhead(bits) of about 2 percent and proposed method effective reduce or eliminate trailing artifact
