Compression Scheme of Graphiclike Image Sequences

Abstract: In order to realize the computer screen share in distant teaching,distant stocking and distant cooperation working,a compression scheme is proposed for graphiclike image sequences(GISS) in this paper.It first converts the graphiclike image to index image,then codes them with interframe run length algorithm and adaptive predictive Huffman algorithm,finally we code stream with LZ77 algorithm.The scheme employs the intrinsic characters of the GISS——the color distribution of the image mainly concentrates on few kinds of color and the pixels which have the same color are also adjacent in space.The result of computer simulation shows that our sheme can compress the GISS effectively and improves the compression ratio obviously relative to the traditional lossless compression algorithms.The most compression ratio is 80:1.
