The fractal image compression method is investigated. Among various coding methods, it allows to get the highest compression ratios. The mathematical model is considered, and classical algorithm of image coding-decoding using the fractal method is presented. Its essence lies in searching self-similar image parts based on compression parameters. Since the coding process using this method requires significant computational cost, its speed is low. It should be noted that image decoding does not need large capacity and resources of the operating system. Low compression speed is caused by the fact that high quality of the output image requires handling a large number of domain areas. So, studies on searching criteria that allow to select a suitable domain area that after affine transformations most closely approximates the rank region are relevant.A brief analysis of methods for optimizing and improving the speed of building iterated function systems of fractal image coding, their efficiency and practical application possibility is performed.
