Jianbiao Wang · Journal of Changchun Post and Telecommunication Institute · 2003
With analyzing the availability of fractal image coding and the characters of affine transform in wavelet domain, a fractal image coding approach based on classifications is presented in this paper. Simulation results show that the proposed approach can simplify the encoding parameters, raise the compression rate while maintaining good image quality. In the meantime, it can speed up the encoding time by combining the characters of automatic classifications in wavelet domain.
