Abstract

A method for deriving motion vector is provided, this method includes: obtaining a space domain motion vector prediction and a time domain motion vector prediction of adjacent blocks of a coding unit in a predetermined direction; performing a filtering operation on the space domain motion vector and the time domain motion vector prediction to obtain the space domain motion vector prediction and the time domain motion vector prediction of the filtered adjacent blocks; determining, according to a predetermined inter-frame prediction mode, reference motion vectors of a current block in four side directions by using the space domain motion vector prediction and the time domain motion vector prediction of the filtered adjacent blocks and a coordinate position of the current block in the coding unit; and deriving motion vectors of the current block according to the reference motion vectors and the coordinate position of the current block in the coding unit.
