Abstract
A method of decoding includes receiving a bitstream in which a current image is encoded, dividing the current image based on a plurality of division types pre-defined in the decoding apparatus, and decoding the divided current image based on coding information extracted from the bitstream wherein the current image is divided into a plurality of division units based on at least one of horizontal lines or vertical lines. At least one of the horizontal lines has a length shorter than a width of the current image or at least one of the vertical lines has a length shorter than a height of the current image.
Claims10
An image decoding method, comprising:
- generating a prediction block by predicting a current block from a bitstream;
- generating a residual block for the current block from the bitstream;
- decoding a picture including the current block based on the prediction block and the residual block;
- obtaining, from the bitstream, reconstruction information for the decoded picture;
- and
- rearranging samples in the decoded picture based on the reconstruction information,
- wherein the rearranging is performed by flipping or rotating the samples, and
- wherein the bitstream includes projection information for mapping the decoded picture to a three-dimensional coordinate system.
An image encoding method, comprising:
- generating a prediction block of a current block;
- generating a residual block for the current block based on the prediction block;
- encoding a picture including the current block based on the residual block;
- encoding reconstruction information related to rearranging samples of the picture;
- encoding projection information for mapping the picture to a three-dimensional coordinate system;
- and
- generating a bitstream comprising the transform information and the projection information,
