Abstract

Finding the optimal algorithm between an efficient encoding process and the rate distortion is the main research in fractal image compression theory. A new method has been proposed in this paper based on the optimization ofthe LeastSquare Error and the orthogonal projection. A large number ofdomain blocks can be eliminated, in order to speed-up fractal image compression. Moreover, since the rate-distortion performance ofthe most fractal image coders is not satisfactory, a n efficient bit allocation algorithm to improve the rate distortion is also proposed. Some implementation and comparison have been done with the feature extraction method to prove the efficiency ofthe proposed method.
