Document Type and Number:
WIPO Patent Application WO/2023/123284
Kind Code:
A1
Abstract:
An embodiment of the application provides a decoding method, an encoding method, a decoder, an encoder, and a storage medium. By means of parsing a stream of data, determine an attribute residual error value of a color component corresponding to a current point; acquire an attribute prediction value of a color component corresponding to a current point; determine a prediction model of a color component of a current point; wherein, the prediction model is determined on the basis of a degree of difference between color components; decoding and reconstructing the color component of the current point on the basis of the prediction model, the attribute residual error value, the attribute prediction value and the initial cross-component attribute residual error prediction value, obtaining an attribute reconstruction value of the color component.
