| Abstract: | The principles and features of the fractal coding and the wavelet transforms are analyzed.By the integration of wavelet transforms and fractal coding and by use of self-similarities,the image compression coding based on wavelet transforms and fractal coding is proposed with the iterated function system.This approach can significantly reduce the computation complexity and encoding time.A set of experiments and simulations show the proposed method has good performance within a broad compression rate scale.The potentials of using the technique for further improvement are pointed out. |
