Abstract
Provide are an inter prediction method, encoder, decoder, and storage medium. Said method comprises: determining a prediction mode parameter of the current block; when the prediction mode parameter indicates a geometrical partitioning prediction mode is used for determining inter prediction of the current block, determining a geometrical partitioning prediction mode parameter of the current block; according to the geometrical partitioning prediction mode parameter, determining a first and a second prediction value and a weight index corresponding to the sample in the current block; clipping the weight index corresponding to the sample in the current block to obtain absolute information of the weight index; determining a first and a second weight value based on absolute information of the weight index; and determining an inter prediction of the sample of the current block according to weighted combination of the first prediction value, first weight value, second prediction value and second weight value.
