THREE-FRAME MOTION ESTIMATOR FOR RESTORATION OF SINGLE FRAME DAMAGES

摘要

A method for reconstructing damaged areas in a single frame of digital motion pictures, where damaged pixels in a current frame (C) are reconstructed using motion compensation based on a motion estimator. The motion estimator comprises a motion vector selection using a combined measure for evaluating linear motion over three frames, going from a previous frame (P) to a next frame (N) through the current frame (C). Compared to a virtual frame motion estimator, the method according to the invention achieves better stability and confidence in the motion search. Compared to the use of a standard motion estimators, the method according to the invention has a better way of finding the correct motion for the damaged areas whether unknown or known, while still being able to find the correct motion for those parts which are not damaged.
