篒n this paper，a novel efficient coding scheme is proposed as the newly developed fractal technique is applied to the sequence image coding．In order to improve thedecoded image quality，a new affine transform is also proposed．The contractlvlty condition is analyzed and the optimal parameters of the affine transform is derived in the paper．txperlmental results show that as for the international standard test sequence“Miss America”，the compression performance achieved is quite satisfied．
