Abstract: In a method for video coding in a decoder, prediction information of a current block of a current picture in a coded bitstream is decoded. The prediction information indicates a geometric partitioning mode (GPM) for the current block. The current block is partitioned into two partitions in the GPM mode, and each of the partitions is associated with a respective predictor. A weighting index for a sample of the current block is determined based on a position of the sample. A weighting factor is calculated based on the weighting index of the sample according to an equation that converts the weighting index to the weighting factor. The calculation includes performing a right shift operation based at least on a sum of the weighting index and an offset value, and clipping a result of the right shift operation to be within a predefined range. The sample is reconstructed based on the weighting factor and the predictor corresponding to the sample.
