1. A method for decoding a 360-degree image, the method comprising:
receiving a bitstream in which the 360-degree image is encoded, the bitstream including data of an extended 2-dimensional image, the extended 2-dimensional image including a 2-dimensional image and a predetermined extension region, and the 2-dimensional image being projected from an image with a 3-dimensional projection structure and including at least one face; and
reconstructing the extended 2-dimensional image by adding a residual image for the extended 2-dimensional image to a predicted image for the extended 2-dimensional image, the predicted image being obtained by inter prediction,
wherein a size of the extension region to be padded is determined based on first width information of the extension region on a left side of the face and second width information of the extension region on a right side of the face, both the first width information and the second width information being obtained from the bitstream, and
wherein sample values of the extension region are determined differently according to a padding method selected from a plurality of padding methods.
