Title:
VIDEO DECODING METHOD, VIDEO ENCODING METHOD, RELATED DEVICES, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/116824
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a video decoding method, a video encoding method, related devices, and a storage medium. The video decoding method comprises: determining, in the current coding unit of the current image, the current string to be decoded; if the current string is a unit vector string and the current string comprises a first pixel, determining a reference pixel of the first pixel from a historical decoding unit in the current image, wherein the historical decoding unit is a decoded coding unit adjacent to the current coding unit in the current image, and the reference pixel of the first pixel and the first pixel are adjacent in the current image; and according to a reconstruction value of the reference pixel of the first pixel, obtaining a prediction value of the first pixel to obtain a decoded image. The embodiments of the present application can effectively expand the application range of the unit vector string, and is helpful for improving the encoding and decoding performance.
