Abstract
This chapter presents an approach to unsupervised digital movie restoration. The approach is based on the idea of recovering the appearance of color instead of the original color signal. The rationale behind this choice is that very often the original color reference is missing in old films, and new films or digital coding can be subject to important gamut transformations. The authors apply algorithms that are designed to reflect the capabilities of the human vision system in automatically adjusting color and lightness variation in the scene.
