Abstract

Provided are an image encoding/decoding method, a bitstream transmission method, and a computer-readable recording medium storing a bitstream. The image decoding method according to the present disclosure comprises the steps of: generating a prediction block of the current block on the basis of a prediction mode of the current block; generating a reconstructed sample of the current block on the basis of the prediction block; and performing filtering on the reconstructed sample, wherein the step of generating the prediction block comprises the steps of: deriving a basic prediction block of the current block; deriving a multi-reference block of the current block; and generating a final prediction block of the current block by weighted-summing of the basic prediction block and the multi-reference block, and a filter strength used for the filtering is determined on the basis of prediction information related to the current block, the prediction block, or the multi-reference block.
