Claim 0:
1. A method of decoding an image, the method comprising:
decoding, from a bitstream, motion vector refinement information indicating whether to refine motion vectors of blocks in a current sequence;
determining a motion vector candidate list of a current block based on a neighboring block of the current block;
decoding, from the bitstream, motion vector prediction information of the current block in the current sequence;
determining a motion vector of the current block based on the motion vector candidate list and the motion vector prediction information of the current block;
refining the motion vector of the current block based on the motion vector refinement information; and
reconstructing the current block based on the refined motion vector of the current block,
wherein the motion vector is refined according to a size of the current block.
