METHOD AND APPARATUS FOR ENCODING VIDEO BY MOTION PREDICTION USING ARBITRARY REGION, AND METHOD AND APPARATUS FOR DECODING VIDEO BY MOTION PREDICTION USING ARBITRARY REGION Russian patent published in 2014 - IPC H04N19/61 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to video encoding and decoding. The invention discloses a method and an apparatus for encoding video, wherein the method involves encoding video data of a maximum encoding element based on deeper encoding elements of hierarchical structures in accordance with at least one area for dividing the maximum encoding element, while performing inter-prediction using regions obtained by dividing the encoding element according to arbitrary ratios, and determining the encoding depth; and outputting a bit stream which includes encoded video data corresponding to the encoding depth, and in accordance with the maximum encoding element and information relating to the encoding depth and encoding modes.

EFFECT: efficient encoding and reconstruction owing to use of a size of the encoding element and an encoding mode which are adaptively determined in accordance with image data characteristics.
