FIELD: physics, video.SUBSTANCE: invention relates to techniques for encoding and decoding video images. Disclosed is a method of encoding image information containing motion data by selecting a motion vector from a group of at least three possible motion vectors for at least one current unit of a current image to be encoded. The method includes a step of determining an optimum selection subgroup comprising part of the possible motion vectors. Further, the method includes selecting a motion vector from the vectors of the optimum selection subgroup and inputting into said information data on allocation of a motion vector selected from the vectors of the optimum selection subgroup.EFFECT: high efficiency of encoding and decoding video images by determining an optimum selection subgroup containing part of possible motion vectors.12 cl, 8 dwg |
