METHOD OF COMPRESSION OF GRAPHIC FILE BY FRACTAL METHOD USING RING CLASSIFICATION OF SEGMENTS

摘要

FIELD: information technology.;SUBSTANCE: method of compression of graphic file by fractal method using ring classification of segments, in which the graphic file is split into rank regions and domains, and for each rank region the domain and the corresponding affine transformation is found, that best approximates it to the appropriate rank region, and using the obtained values of the domain parameters, comprising their coordinates, the coefficients of the affine transformations, the values of brightness and contrast, the archive is formed, and classification of domains and rank regions are introduced, based on the allocation in them of the "rings" and the calculation of the mathematical expectation of pixel intensity of these "rings", which enables to reduce the complexity of the phase of correlation of the segments and to accelerate compression.;EFFECT: reduced time of compression of the graphic file by fractal method.;3 dwg
