1. A method for performing multihypothesis prediction during video coding of a coding unit, the method comprising:
processing a plurality of sub-coding units in the coding unit; performing disparity vector (DV) derivation when the coding unit is processed by a three-dimensional (3D) or multi-view coding tool, or performing block vector (BV) derivation when the coding unit is processed by intra picture block copy (IntraBC) mode, wherein the step of performing DV or BV derivation further comprises:
deriving a plurality of vectors for multihypothesis prediction of a specific sub-coding unit in the coding unit, wherein the plurality of vectors are selecting from at least two DVs, at least two BVs, or a combination of DV, BV, and motion vector (MV), at least one of the vectors is the DV or BV of one other sub-coding/coding unit, and the one other sub-coding/coding unit is coded before the corresponding DV or BV is derived for multihypothesis prediction of the specific sub-coding unit; and performing multihypothesis prediction on the specific sub-coding unit according to the plurality of vectors, wherein the step of performing multihypothesis prediction on the specific sub-coding unit according to the plurality of vectors further comprises:
utilizing a linear combination of a plurality of pixel values derived from the plurality of vectors as a predicted pixel value of the specific sub-coding unit. |
