Abstract
In a motion estimation for a group of at least one image element in a frame of a video sequence, a global motion is determined between the frame and a reference frame. Uncovered groups present in an uncovered region of the frame are identified based on the determined global motion. The global motion is assigned as motion representation for these identified uncovered groups. The assigned motion representation is useful for constructing new frames in the sequence in a frame rate up-conversion.
