Disclosed are a method for encoding/decoding an image and a recording medium storing a bitstream. A method of decoding an image includes: segmenting a current block in an image into a plurality of partitions including a first partition and a second partition based on a predetermined segmentation line; determining a first reference block of a first partition and a second reference block of a second partition based on motion information of the current block; a current pixel in a current block is predicted by applying a predetermined weighting value to a first pixel belonging to a first reference block and a second pixel belonging to a second reference block, the predetermined weighting value being determined as one of a plurality of weighting value candidates based on a position of the current pixel in the current block, and the weighting value candidates being determined as one of a plurality of weighting value candidates based on a position of the current pixel in the current block. Each weighting value candi
