In order to reduce the coding time of tradition method,a fast sequence image fractal compression algorithm is presented in this paper. Based on the principle of optimal fuzzy clustering (OFC), this technique clearly outperform to the classic method relying on reduction of the size of domain pool by classification. In computer simulation, the OFC-based algorithm for the fractal coding scheme achieve excellent performance. For some standard and medical sequence image, the results denote that the encoding speed is improved about 5 times faster than the conventional fractal image coding in case of the fixed compression ratio and the quality of the reconstructed image can be better retained.
