Abstract:
In a motion estimation for a group (12) of at least one image element (11) in a frame (10) of a video sequence (1), a global motion (50) is determined between the frame (10) and a reference frame (20). Uncovered groups (12, 14) present in an uncovered region (13) of the frame (10) are identified based on the determined global motion (50). The global motion (50) is assigned as motion representation for these identified uncovered groups (12, 14). The assigned motion representation is useful for constructing new frames (30) in the sequence (1) in a frame rate up-conversion.
