Abstract :
This paper proposes a novel algorithm developed specifically for removing colour cast from faded photographic materials. The algorithm is fully automated and requires no initial training. Quality of restored images is evaluated both subjectively, using human subjects, and objectively, using a mathematical model. Results indicate that the algorithm is capable of restoring a wide range of indoor and outdoor scenes.
