Title: IMAGE ENCODING/DECODING METHOD AND DEVICE THEREFOR
Abstract:
The present invention discloses an image encoding/decoding method and a device therefor. In detail, a method for decoding an image by means of a decoding device includes: a step for deriving an intra-prediction mode of a current block; a step for configuring reference samples from samples neighboring on the upper side of the current block and samples neighboring on the left side; a step for generating prediction samples of the current block by using the reference samples; and a step for filtering samples adjacent to the upper boundary and/or left boundary of the current block among the prediction samples, wherein, when the current block is a non-square block, whether or not to filter the samples adjacent to the upper boundary of the current block can be determined considering only the width of the current block, and whether or not to filter the samples adjacent to the left boundary of the current block can be determined considering only the height of the current block.
