The state of the art movie restoration methods compensate the motion by an optical flow estimate and then filter out the compensated
movie. Now, the motion estimation problem is fundamentally ill-posed. This fact is known as the aperture problem: trajectories are
ambiguous since they could coincide with any promenade in the space-time isophote surface.
In this talk, we show that the aperture problem can be taken advantage of. This observation leads to use for movies the recently
