碩士 === 大同大學 === 通訊工程研究所 === 96 === The no search fractal image coding method is very fast compared with the full search fractal image coding method. In this thesis, we propose no search fractal coding in wavelet domain method that can make encoding speed faster and have high compression ratio. This method uses fractal code on wavelet domain. Encoded image range blocks utilize fixed location domain blocks in different wavelet scale. We utilize the correlation of different wavelet scale to reduce encoding time. Experiment result show that the encoding time of proposed method is faster than the no search method and searchless in wavelet domain. It is show that the compression ratio and the reconstructed quality of our method are better than the method of searchless fractal coding in wavelet domain.
