摘要： 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.

摘要： A method and apparatus use a geometric modified image for video encoding/decoding. The encoding method may include: generating a geometric modified reference picture by geometrically modifying a reference picture; generating a prediction block of a current block within an encoding target picture by performing inter prediction by referencing the reference picture or the geometrically modified reference picture; and encoding inter-prediction information of the current block.

摘要： An image is decoded by deriving a first candidate list for the current block by using motion information of neighboring blocks of the current block; deriving a second candidate list for the current block by using previously reconstructed motion information; deriving a third candidate list by using the first candidate list and the second candidate list; and deriving a prediction block for the current block by using the third candidate list.
