Abstract

Official abstract text for this publication.

A method for decoding a 360-degree image includes: receiving a bitstream obtained by encoding a 360-degree image; generating a prediction image by making reference to syntax information obtained from the received bitstream; combining the generated prediction image with a residual image obtained by dequantizing and inverse-transforming the bitstream, so as to obtain a decoded image; and reconstructing the decoded image into a 360-degree image according to a projection format. Here, generating the prediction image includes: checking, from the syntax information, prediction mode accuracy for a current block to be decoded; determining whether the checked prediction mode accuracy corresponds to most probable mode (MPM) information obtained from the syntax information; and when the checked prediction mode accuracy does not correspond to the MPM information, reconfiguring the MPM information according to the prediction mode accuracy for the current block.

First claim

Opening claim text (preview).

What is claimed is: 1 . An image decoding method performed by an image decoding apparatus, the image decoding method comprising: receiving a bitstream in which an image is encoded; obtaining index information for specifying a block division type of a current block in the image from the bitstream; determining the block division type of the current block from a candidate group pre-defined in the image decoding apparatus based on the index information; dividing the current bl…
