Abstract: The invention relates to a method for encoding/decoding an image. The image decoding method according to the invention comprises the steps of: obtaining diagonal partition information on a current block; determining a diagonal partition structure of the current block using the diagonal partition information; and diagonally partitioning the current block into a first and a second area based on the determined diagonal partition structure, the current block being a leaf node of a square or rectangular partition.
