Abstract
Methods, encoders, and decoders with localized weighted prediction are disclosed. A decoding method includes decoding data for a current segment to generate decoded data including residuals and a weighted prediction parameter for the current segment. A weighted prediction for the current segment is generated based on the weighted prediction parameter. A predictor for the current segment is generated by intra/inter prediction. The weighted prediction and the predictor are combined to obtain a modified predictor, and the current segment is reconstructed according to the modified predictor and the residuals.
