Abstract
In this work, it is shown that a fractal image coding can be placed in a conventional predictive framework by using a wavelet representation. This has the significant advantage of simplifying decoding by avoiding iteration and of relating the technique to traditional coding methods. The resulting coder is a combination of transform and predictive techniques. A novel frequency domain subblock search is presented along with a tree-structures vector quantizer. Some results are prsented for a variety of images and bit-rates followed by some speculation on further research.
