FIELD: information technology.
SUBSTANCE: coding element is corrected based on image characteristics with simultaneous enlargement of the maximum size of the coding element taking into account the size of the image. The method of decoding video includes a step of receiving and analysing the bit stream of an encoded image. The method also includes determining coding elements having a hierarchical structure, which are data entities in which the encoded image is decoded. The method also includes determining sub-elements for predicting coding elements using information indicating the form of division of coding elements and information on prediction elements of coding elements obtained via analysis from the received bit stream. The sub-elements have regions obtained by dividing at least either the height or the width of coding elements according to arbitrary ratios.
EFFECT: high efficiency of encoding and decoding video images.
