Patent ID: 8254439

Claim:
A motion vector correction method for correcting an estimated motion vector for a pixel located at a position of an interpolated frame between a first frame and a second frame of a video sequence, comprising: estimating a previous motion vector field and a following motion vector field, wherein the previous motion vector field is estimated on the basis of the first frame, the second frame and a third frame preceding the second frame and the following motion vector field is estimated on the basis of the first frame, the second frame and a fourth frame following the first frame; determining a set of reference motion vectors associated with the first frame and the second frame for the position of the pixel, wherein the set of reference motion vectors comprises a first motion vector set as the estimated motion vector and a pair of corresponding motion vectors respectively from the previous motion vector field and the following motion vector field; obtaining a measure of consistency between the pair of corresponding motion vectors; adapting a plurality of weighted factors respectively associated with the set of reference motion vectors according to the measure of consistency; and correcting the estimated motion vector according to the adapted weighted factors and the set of reference motion vectors.
