Abstract

One of major tasks of modern information theory is the development and realization of new methods of compression, which provide the maximal level of compression with simultaneous minimization of level of distortions in the rebuild informative structure.The algorithm of restoration of images, based on the method of decoding by the amount of bit changes, is developed. The substantiation of choice of the stages of decompression processing procedure, based on the method of decoding by the amount of bit changes, is provided. The basic general stages of algorithm of restoration of images were defined, they are: decoding of compressed data, dequantum of image transforms, inverse transformation of colour component, presentation of initial image by a colour model. The estimation of quality of rebuild images on the base of value peak signal/noise ratio is provided. The results allow to come to the conclusion, that the offered algorithm of compression-decompression of coloured images brings in curvatures in the admissible limits of sensitiveness of human organs.
