Cascade fractal image compression and its modification

We propose an approach to fractal image compression that provides fast decoding of the compressed image in one iteration and allows knowing the accurate value of the error contributed by each range block to the collage error at each step of partition scheme optimization. A modification of this metho...

Description
Summary:We propose an approach to fractal image compression that provides fast decoding of the compressed image in one iteration and allows knowing the accurate value of the error contributed by each range block to the collage error at each step of partition scheme optimization. A modification of this method assuming equal sizes of domain and range blocks is considered. The results of the proposed approach application to test images are analyzed. The further research directions are discussed.
