Abstract
This disclosure provides systems, apparatus, and methods for determining prediction weights for merge modes. One exemplary method includes: determining weights for at least one of inherited affine merge candidates, constructed affine merge candidates, or zero motion vectors of a coding unit; and bidirectionally predicting the coding unit based on the determined weights. The weights for the current coding unit may be determined through explicit signaling of weighting indicators in the bitstream or through implicit derivation at the decoder side.
