Implementation:    Konstantin Strelnikov

Video, captured without special auxiliary device, video captured on vehicle (car, helicopter) often has undesirable motion of whole frame - shake. Video with shaking is very disagreeable to watch. MSU Deshaker filter is intended for undesirable motion removing, in other words for video stabilization.

Frames shift so as to remove undesirable motion when video stabilization is performed. Thus unknown areas are appearing near the frame edges (see figure 1). Merit of the filter in unknown areas reconstruction from previous frames.
