    Abstract:

    In this paper, a color image fractal compression coding method is proposed by analyzing the correlation of r, g, b components of a color image and the remnant of layer information in quadtree scheme. It merges three-color components into one. Accordingly this method will reduce the matching blocks, which need to be saved and encoded by SFC (separated fractal coding) algorithm, into one and at one time the source data and layer information in quadtree scheme can sustain non-losses and high-proportion compression. Furthermore, by selecting different combinations, a series of coding methods that bear very close compression ratio and quality of decoded image are obtained. Moreover the coding speed of the luminosity method among them is faster than the other ones. Experimental results indicate that this approach excels SFC or standard JPEG and can be a good color image fractal compression algorithm.
