Title:
CODING AND DECODING METHOD AND CODING AND DECODING APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/077616
Kind Code:
A1
Abstract:
The present application provides a coding and decoding method, a coding and decoding apparatus, a device, and a storage medium. According to a hierarchical prediction structure of a multi-viewpoint array, at least one viewpoint of a first hierarchy is first subjected to predictive coding in a frame coding process to obtain a reference frame, and then viewpoints of a second hierarchy are subjected to predictive coding according to the reference frame to obtain a reconstructed image, so that a reference relationship among viewpoints at different positions (such as different rows or different columns) of the second hierarchy and the first hierarchy can be established, and the spatial position correlation among the viewpoints in the two-dimensional distribution can be better used, thereby facilitating the improvement of the video compression efficiency of the multi-viewpoint array.
