Abstract: Disclosed are an image coding/decoding method and an apparatus therefor. Specifically, a method for decoding an image by a decoding apparatus may include: deriving an intra prediction mode of a current block; configuring reference samples with samples neighboring to an upper end and samples neighboring to a left side of the current block; generating a prediction block of the current block by using the reference sample; and filtering a sample adjacent to a top boundary and/or a left boundary of the current block among the prediction samples, in which when the current block is a non-square block, whether to filter the sample adjacent to the top boundary of the current block may be determined by considering only a width of the current block and whether to filter the sample adjacent to the left boundary of the current block may be determined by considering only a height of the current block.
