Abstract :
The interest in image compression by means of fractal techniques has been steadily growing in recent years since Jaquin proposed a fully automatic image compression algorithm called fractal block coding (FBC). In this paper, we introduce a hybrid system where only the edge region of the image is coded by fractal transform and the smooth region is modeled by other techniques. The non-fractal coded region is used to help the coding of the fractal coded region, so that the fractal coded region can be represented by fewer bits. Experiments show that the overall coding efficiency is improved
