Abstract

The present invention relates to an image decoding method. The image decoding method comprises deriving initial motion information of a current block from at least one of motion information of a spatial neighbor block, motion information of a temporal neighbor block, and pre-defined motion information, generating refined motion information by performing motion information refinement for the initial motion information and generating a prediction block of the current block by using the refined motion information.
