FIELD: physics, image processing.
SUBSTANCE: invention is related to method of reduction of redundancy of transmitted information. Invention actually consists in creation of method for additional information transmission at fractal coding of images. Transmission of additional information is carried out in the following manner: whenever initial image is compressed with the help of fractal compression method, in indices of domain units orientation binary sequence of three digits is recorded, which represents additional information, then based on this additional information processed domain is turned and brightness coefficients - o and contrast coefficients - s are searched for by method of least squares, which correspond to optimal values, at which the following expression is minimised: 
where {dij} and {rij} accordingly are values of pixels in domain and range areas, as a result of which optimal domain is found with account of inbuilt additional information for coding of range unit, after that indices of domains, coefficients of brightness and contrast, additional information are sent through communication channel. On receiving side additional information is separated and initial image is restored.
EFFECT: creation of method for additional information transmission with fractal coding of images.
