摘要： Disclosed herein is an image encoding/decoding method. A method of decoding an image includes determining an intra prediction mode of a current block, and generating a prediction block of the current block, by performing prediction based on the intra prediction mode. When the intra prediction mode of the current block is a matrix-based intra prediction (MIP) mode, a length of a reference sample used for intra prediction is derived based on a length of the current block.

摘要： The present invention relates to an image information decoding method. The decoding method includes receiving a bit stream including a network abstraction layer (NAL) unit that includes information related to an encoded image, and parsing a NAL unit header of the NAL unit. The NAL unit header may not include 1-bit flag information that represents whether a picture is a non-reference picture or a reference picture in the entire bit stream during encoding.

摘要： Disclosed is an image encoding method. The method includes deriving a motion refinement candidate from among motion information of spatial neighboring blocks, motion information of a temporal neighboring blocks, predefined motion information, and motion information that most frequently occurs in a reference picture, performing a motion information refinement on the derived motion refinement candidate, and generating a prediction block of a current block by using the motion refinement candidate having undergone the motion information refinement.
