Method, device, and system for determining prediction weight for merge mode

Abstract:

Systems, devices, and methods for determining prediction weight for merge mode are disclosed. One exemplary method comprises: determining a weight for at least one of an inherited affine merge candidate, a constructed affine merge candidate, or a zero motion vector of a coding unit; and bi-predicting the coding unit based on the determined weight. The weight of a current coding unit can be determined through explicitly signaling a weight index in the bitstream, or through implicit derivation at the decoder side.
