Abstract It is extremely needed to conserve and restore old films. Intensity flicker is a common artifact in old black-and-white film sequences. Unfortunately, the existing algorithms removing intensity flicker do not consider the effect of local motion. To improve this point, a method based on the cosine basis and the successive over-relaxation is developed in this paper. Both local motion and local flicker are considered in this method. Experiments for real-world old film sequences shows that the result is satisfactory.
