| Abstract: | Fractal image coding methods open up great Prospects for image coding. In this pepercommon fractal image coding methods are studied at first. Some shortcomings of them are found andcorrected with a new method . The new method is improved further in DCT domain. The new method reducescompression time greatly and the quality of decoded images is much better than the quality of decodedimages compressed by the common fractal image methods at the same comprasion ratio.Coding results showthe advantuge of the fractal image coding method in DCT domain. |
