Abstract: An image encoding/decoding method and apparatus are provided. An image encoding method performed by an image encoding apparatus may comprise determining an intra-prediction mode of a current block, configuring a reference sample of intra prediction by using at least one of a neighbor pixel of the current block in a current picture and a pixel of a reference picture, and performing intra prediction for the current block based on the intra-prediction mode and the reference sample.

Abstract: There is provided a method of decoding an image, the method comprising: decoding information for motion information prediction of a current block from a bitstream, predicting motion information of the current block based on the information, refining motion information of the current block by using the decoded information and the predicted motion information of the current block and reconstructing the current block based on the refined motion information of the current block.
