The merits and drawbacks of fractal image compression in comparison to jpeg and other methods are outlined in 43, 30, 39. The fractal image compression is a recent tool for encoding natural images. Pdf fractal image compression using the biological model. Fractal compression is a lossy compression method for digital images, based on fractals. Mandelbrot and the 1977 publication of his book the fractal geometry of nature.
Pdf the paper gives and introduction on image coding based on fractals and develops a simple algorithm to be used as a reference design. Fractal image compression allows fast decoding, but encoding is very slow. The method is best for textures and natural images, which is. Both the methods are found to compete with the standard fractal image compression algorithms. Fractal image compression is based on the observation that realworld images in general are rich in afflne redundancy. An introduction to fractal image compression 3 a common feature of these transformations that run in a loop back mode is that for a given initial image each image is formed from a transformed and reduced copies of itself, and hence it must have detail at every scale.

Fisher, fractal image compression, springerverlag, new york, 1995. Fractal coding is a lossy image compression technique, which encodes the image in a way that would require less storage space using the selfsimilar nature of the image. Fractal image compression is a technique based on the representation of an image by a contractive transform, on the space of images, for which the fixed point is close to the original image. Fractal coding is used for compression of medical images 5. Hutchinson, fractals and selfsimilarity, indiana univ.
