Spiral architecture based fractal image compression is proposed in this paper. Perceptually, a new definition of range block and domain block is presented on such enhanced image structure. Compared with the common square image architecture, spiral architecture provides higher fidelity to fractal image compression, which is demonstrated by the experimental results
In this paper, we propose a fractal image compression method on a virtual hexagonal image structure by adopting Fisher's basic method on the traditional square image structure. The modification on the definition of range block and domain block is implemented in order to utilize the enhanced image structure. The results of the proposed approach applied to testing images are analyzed and higher fidelity...
