摘要：
Fractal image coding is a novel way in image compression community, for which quite a number of algorithms or schemes have been devised during the, last decade. In this paper, we propose a general framework model after the overview of principal publishments, which helps to understand common problems and. design effective schemes. An implementation on this model with free-shaped region partition is also introduced. Our highly image-adaptive scheme can achieve coding gains of 1.0-1.5 dB for compression ratios larger than 10:1 in comparison with conventional quadtree scheme.
