VORAUSGERICHTETE BEWEGUNGSVEKTORINTERPOLATION ZUR REDUZIERUNG VON VIDEOARTEFAKTEN |
摘要 |
In a video processing system where motion vectors are estimated for a subset of the blocks of data forming a video frame, and motion vectors are interpolated for the remainder of the blocks of the frame, a method includes determining, for at least at least one block of the current frame for which a motion vector is not estimated (204), whether a block to the left or right has an estimated zero motion vector (206), determining whether the at least one block had an estimated zero motion vector in a previous frame (206), and if both determinations are affirmative (208), providing a predetermined motion vector for the at least one block. The predetermined motion vector may be a zero motion vector (208). |
