Motion picture is not only a theatrical art but also a vivid record of past life. Unfortunately, almost all color films amde since the 1950s are subject to fading that can be arrested only by storing prints at very low temperatures. Photochemical restoration of faded motion prints is impossible. Nowadays, the improvement of computer power allows us to expect digital restoration of motion pictures as acceptable rates. In this paper we present two orginal techniques for restoring faded color image sequences: an assisted and an automated one. The first method consists, in choosing a "reference image" from the sequence, after removing side absorptions introduced by the scanning process, adjusting its colors and contrast, then propagating the correction performed to the whole image sequence. The second method consists in reviving the colors of the image (color enhancement), then balancing them.
