Attractor image compression with a fast non-iterative decoding algorithm

摘要: The problem of decoder convergence speed in an attractor (fractal-based) image compression system is considered. general principles such a are described the context discrete linear spaces. A with previous implementations that decoding rests on iterative procedure whose complexity image-dependent. It shown how this can be sidestepped by introducing modification providing iteration-free decoder. coding results not affected modification. new algorithm requires only one multiplication and three additions per pixel. suitable for applications where fast display images essential, as retrieval from compressed databases. >
