Image data encoding/decoding method and apparatus

Abstract

Disclosed is an image data encoding / decoding method and apparatus. The image decoding method performed by the image decoding apparatus includes: acquiring at least one offset of a picture; deriving a variable for scaling the picture based on the at least one offset; and performing inter prediction on the basis of variables for scaling the picture, wherein at least one offset is defined in the direction of scaling.

Description

[0001] This divisional application is a divisional application with an application date of October 10, 2017, an application number of 201780073622.9, and an invention title of "Image Data Encoding / Decoding Method and Device". technical field [0002] The present invention relates to image data encoding and decoding technologies, and more particularly, to methods and devices for encoding and decoding 360-degree images of real media services. Background technique [0003] With the popularization of the Internet and mobile terminals and the development of information and communication technology, the use of multimedia data is increasing rapidly. Recently, demands for high-quality images and high-resolution images such as high-definition (HD) images and ultra-high-definition (UHD) images have arisen in various fields, and realities such as virtual reality, augmented reality, etc. The demand for media services is also increasing rapidly. Specifically, since multi-view images cap...

AI Technical Summary

Problems solved by technology

Specifically, since multi-view images captured with a plurality of cameras are processed for 360-degree images of virtual reality and augmented reality, the amount of data generated for processing is greatly increased, but the performance of the image processing system for processing a large amount of data insufficient
