Apparatus and methods for motion vector correction |
摘要 |
A motion vector correction apparatus for correcting an estimated motion vector for a pixel located at a position of an interpolated frame between a first and a second frame is provided, including a three-frame motion estimation unit estimating a previous and a following motion vector fields; a motion vector selection unit determining a set of reference motion vectors associated with the first and second frame for the position of the pixel, wherein the reference motion vectors include a first motion vector set as the estimated motion vector and a pair of corresponding motion vectors from the previous and following motion vector fields; and a motion vector correction unit obtaining a measure of consistency between the corresponding motion vectors, adapting a plurality of weighted factors 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.
