1. A method of motion estimation for a group of at least one image element in a frame associated with a time instance in a video sequence, said method comprising the steps of: determining a representation of a global motion of image element property values from at least a portion of a previous frame associated with a previous time instance in said video sequence to at least a portion of said frame; identifying an uncovered group of at least one image element in an uncovered region of said frame based on said global motion representation; and assigning said global motion representation to said uncovered group as motion estimation for said uncovered group.
