A METHOD OF AND UNIT FOR ESTIMATING A MOTION VECTOR OF A GROUP OF PIXELS

摘要

A motion estimation unit (200, 300) for estimating a motion vector of a group of pixels of an input image (104) comprises an occlusion detection unit (206) for calculating an occlusion map (116) which is applicable to the input image (104); an intermediate motion estimation unit (202) for estimating a first motion vector for the group of pixels based on the input image (104) and a preceding image (102) and a second motion vector for the group of pixels based on the input image (104) and a succeeding image (106); and an assignment unit (204) for assigning, based on the occlusion map (116), a final motion vector as the motion vector, with the final motion vector derived from the first motion vector or the second motion vector.
