Method and apparatus for motion vector field encoding

摘要

A method of processing data relating to an image in a sequence of digitized images comprises deriving a motion vector field for the image and smoothing the motion vector field by replacing a given motion vector by a new motion vector derived using averaging based on adjoining motion vectors, the method further comprising identifying where motion discontinuities occur in the image and omitting a motion vector or vectors from the averaging if they are separated from the given motion vector by a motion discontinuity.
