Abstract
(EN)
Disclosed in embodiments of the present application are an image prediction method, an encoder, a decoder and a storage medium, the method comprising: determining at least one image component of a current block in an image; pre-processing the at least one image component of the current block to obtain a pre-processed at least one image component; on the basis of the pre-processed at least one image component, constructing a prediction model, the prediction model being used to perform cross-component prediction processing on the at least one image component of the current block.
