Abstract
The present disclosure provides a method and an apparatus for motion vector refinement. An exemplary method includes: determining a plurality of first blocks associated with a first motion vector and a plurality of second blocks associated with a second motion vector; determining a sum of absolute transformed difference (SATD) between one of the plurality of first blocks and one of the plurality of second blocks; and refining the first motion vector and the second motion vector based on the determined SATDs.
