Abstract

A nonartifactual coding and image decoding method relates to information processing presented in a digital form with receiving a coding image without visual artefacts, There is a method that allows removing some artifacts even in the current image occurring at presentation of an original physical image in a digital form. It is possible according to offered method to realize a nonwaste coding and coding with wastes. The method is based on creation of pixel subsets with common number of input image pixels selected by means of a stochastic discretisation which may be realized with various means, creation on the base of specified subset. On the base of the specified subset they form a basic image model, calculate an error between the input image and the subset, archive error data array and write received data required for decoding to the file. In order to restore the image they perform actions analogical to coding in reverse order. During waste-coding they realize reduction of error data array when more or less part of the error spectrum with random noise is changed, which during decoding on the restored image has a form of graininess and diffuseness inherent for example to an usual photography. The technical result is to provide absence of coherent artefacts in the restored image (received during decoding) at simultaneous increase of efficiency of digital image compression without wastes or with wastes or improvement of image compression-quality with providing error character as a random noise during image decoding and obtaining a synthesized error within specified limits dependent on the image compression grade (coefficient) to be reached.
