In this paper a novel image coding scheme, based on coinbination of fractal and vector quantization techniques is proposed. A two-level coding scheme is described. In the first level, a form of vector quantization is employed to get a rough first-order approximation of the image. In the second level, the residual image, produced after subtracting thc first-order approximation limn the original image, is coded using a simple, fixed-block size fractal technique. Using fixed block size, the algorithm has a very simple and regular structure. The benefit of the proposed technique is the reduction of' the computational complexity in comparison to traditional fractal coding, while the image quality is kept i n high levels
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
