Title:
IMAGE DATA ENCODING/DECODING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/066981
Kind Code:
A1
Abstract:
Disclosed is an image data encoding/decoding method and apparatus. A method for decoding a 360-degree image comprises the steps of: 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, the step of generating the prediction image comprises the steps of: performing image extension of a reference picture obtained by reconstructing the bitstream; and generating a prediction image according to intra prediction by making reference to the reference picture extended by the image extension.
