Abstract: Disclosed herein are a method and an apparatus for encoding/decoding an image. The image decoding method according to the present invention includes obtaining prediction information of a current block from a bitstream and, by performing prediction based on the prediction information, generating a prediction block of the current block. Herein, the prediction information includes split prediction information of the current block. The generating of the prediction block includes obtaining a reference sample from a neighboring block of the current block, applying an interpolation filter to the reference sample, and generating the prediction block by using the reference sample to which the interpolation filter is applied. The interpolation filter is determined based on the split prediction information of the current block.

Abstract: Disclosed herein is an image encoding/decoding method and apparatus based on transform. An image decoding method includes determining a horizontal transform type and a vertical transform type of a current block, deriving a residual block of the current block by performing inverse transform with respect to the current block based on the determined horizontal transform type and vertical transform type, and reconstructing the current block based on the residual block. The determining of the horizontal transform type and the vertical transform type is performed based on at least one of a width or a height of the current block regardless of an intra prediction mode of the current block, when the current block is in an intra sub-block partitions (ISP) mode.
