Abstract: A method for processing a video includes determining a horizontal transform type index for a horizontal transform kernel and a vertical transform type index for a vertical transform kernel of a transform block in the video signal, determining a transform region in which a significant transform coefficient exists in the transform block based on the horizontal transform type index, the vertical transform type index, and a size of the transform block, and applying inverse-transform to the transform region based on the horizontal transform type index and the vertical transform type index. A width of the transform region is determined based on a comparison between the horizontal transform type index and a reference value and a height of the transform region is determined based on a comparison between the vertical transform type index and the reference value.

Abstract: An image encoding/decoding method and apparatus are provided. An image decoding method according to the present disclosure comprises determining whether a prediction mode of a current block is an intra block copy (IBC) mode based on information on the prediction mode of the current block, based on the prediction mode of the current block being an IBC mode, deriving motion information of the current block based on motion information of a corresponding block corresponding to the current block, and generating a prediction block for the current block, by performing IBC prediction based on the derived motion information of the current block. Based on absence of motion information of the corresponding block, the motion information of the current block is derived based on default motion information.
