【Abstract】 In this paper,a fractal image coding approach based on non linear transforms is proposed The non linear transforms satisfy a theory of contractive iterated image transformations Simulation results show that this proposed approach can improve bit rate and peak signal noise ratio(PSNR)by comparing with a traditional fractal image coding method更多还原
