FIELD: information technologies.SUBSTANCE: in the method of processing of raster images, including compression of an image by the method of "cut block coding" or its modifications, before the procedure of compressing coding they perform digital filtration, which increases sharpness of the compressed image, and after the decoding procedure they perform smoothing digital filtration of the decoded image.EFFECT: improved quality of decoded raster images when methods used for their compressing coding on the basis of cut block coding or their modifications, improved current formalised criteria.3 cl, 8 dwg |
