Original Abstract Submitted
A method for decoder-side motion vector derivation utilizes a spatial correlation. A video coding method and apparatus minimize discontinuities at block boundaries, in order to overcome disadvantages of motion prediction that performs motion compensation on a per block basis. The video coding method and the apparatus derive, during decoder-side motion vector derivation, motion vectors by taking into account spatial correlation of the current block with surrounding blocks rather than deriving motion vectors by considering only the cost of a current and prediction block.
