FIELD: physics, computer engineering.SUBSTANCE: invention relates to predictive encoding and decoding of a motion vector. The method of encoding a motion vector comprises steps of generating information about the motion vector based on a motion vector of a current block and a motion vector predictor of the current block, generating a virtual motion vector, generating vector differences between the virtual motion vector and the plurality of motion vector predictor candidates, comparing the vector differences with the information about the motion vector, and selectively excluding the second motion vector predictor candidate according to the comparison, and encoding the information about the motion vector and information about the motion vector predictor of the current block.EFFECT: high compression ratio when encoding/decoding an image.15 cl, 16 dwg |
