Abstract
A method for fractal image compression is presented which is an extension of A.E. Jacquin's (1990) algorithm. The proposed algorithm improves Jacquin's block-based algorithm by allowing irregularly shaped fractal transformations. The method for producing these transformations is to start with the block-based approach and then prune the transformations in the transform space. The results show a large improvement in compression ratio over Jacquin's system at the same signal-to-noise ratio. For high compression ratios the system has similar performance to the JPEG (Joint Photographic Experts Group) standard.<>Keywords
