SUBSTANCE: invention relates to coding/decoding of picture signals. Method for variation of reference block (RFBL) with reference pixels in reference picture (I_REF) converts (TRF) reference block to first set of factors (REF (u, v,)). It changes the first set of factors (REF (u, v,)) with the help of one or several weights (TR (u, v,)) and executes the inversion (ITR) of changed.

Application of extra pixels and extra reference pixels allows the determination of spectral weights so that they display the effects of attenuation. Particularly, if reference frame consists of two black-out frames one of which should be forecast with the help of reference frame, then assignment of weights in spectral band allows isolation of significant frame from two frames.

FIELD: technology for processing digital images, namely, encoding and decoding of images.

SUBSTANCE: in the system and the method, serial conversion and encoding of digital images are performed by means of application of transformation with superposition (combination) of several resolutions, ensuring serial visualization and reduction of distortions of image block integrity and image contour when compared to many standard data compression systems. The system contains a converter of color space, block for transformation with superposition of several resolutions, quantizer, scanner and statistical encoder. Transformation by scanning with usage of several resolutions outputs transformation coefficients, for example, first transformation coefficients and second transformation coefficients. Representation with usage of several resolutions may be produced using second transformation coefficients with superposition of several resolutions. The transformer of color space transforms the input image to representation of color space of the input image. Then, the representation of color space of input image is used for transformation with superposition of several resolutions. The quantizer receives first transformation coefficients and/or second transformation coefficients and outputs quantized coefficients for use by scanner and/or statistical encoder. The scanner scans quantized coefficients for creating a one-dimensional vector, which is used by statistical encoder. The statistical encoder encodes quantized coefficients received from quantizer and/or scanner, which results in compression of data.

SUBSTANCE: method contains steps of processing information on the basis of mathematical transformations, divisions of the image into blocks of the image and coding of the current block, and the division of the image is carried out repeatedly on square blocks whose sizes are defined by a mass of initial data. For blocks which are not analysed before, an un-oriented graph is built, whose each top corresponds to one of such blocks, and each block consistently subject to affine transformations. Each transformed block is compared to all other blocks and if the degree of distortions of such a block at replacement of one of other blocks satisfies with it to the set restrictions on quality of the image between corresponding tops the column create an edge for reception the column, minimal covering which the set of tops answers an optimum base subset of blocks. The information is compared with that stored in memory of the block therefore leaving the information on the storage of the image corresponding to the minimal volume of data necessary for restoration of the image, then the procedure is repeated for the next size of the square block.

EFFECT: increase in the factor of compression of the image with minimal loss of quality at its restoration.

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.
