Abstract: Disclosed is a method of decoding an image and a method of encoding an image. The method of decoding an image includes: obtaining motion-constrained tile set information; determining, on the basis of the motion-constrained tile set information, a first boundary region of a collocated tile set within a reference picture, which corresponds to a motion-constrained tile set; padding a second boundary region corresponding to the first boundary region; and performing inter prediction on the motion-constrained tile set by using a collocated tile set that includes the padded second boundary region.

Abstract: Disclosed herein is a method of decoding an image. The method includes determining a prediction mode of a current block as a merge mode with motion vector difference (MMVD), deriving a merge candidate list of the current block, deriving a motion vector predictor of the current block using the merge candidate list, deriving a motion vector difference of the current block, and deriving a motion vector of the current block using the motion vector predictor and the motion vector difference.
