1. A method of decoding an image, the method comprising:
identifying a region by partitioning an image; and
determining one of a plurality of prediction modes as a prediction mode of the region based on a horizontal size of the region, a vertical size of the region and a partition shape indicating a direction in which the region is partitioned,
wherein the plurality of prediction modes comprise inter-prediction and intra-prediction,
wherein the region comprises a plurality of coding blocks
wherein the plurality of coding blocks correspond to a plurality of leaf nodes of a partition tree structure, and
wherein the prediction mode of the region is used as a prediction mode of all of the plurality of leaf nodes of the partition tree structure.
