Abstract
The present disclosure provides a method for inter-frame prediction of a coding unit in an image. The method may include obtaining a first MV candidate list corresponding to the coding unit and the first MV candidate list may be constructed based on a non-triangle prediction mode, such as a merge mode. The method may also include determining, based on the first MV candidate list, a second MV candidate list corresponding to the coding unit. The second MV candidate list may be a triangle candidate list used for inter-prediction using a triangle prediction mode. MVs in the second MV candidate list may be determined based on MVs in the first MV candidate list. The method may also include determining, based on the second MV candidate list, a target prediction unit of the current coding unit according to a triangle prediction mode.
