Restoration of films affected by partial color artefacts

In this paper we present a novel restoration algorithm for a special type of film artefacts resulting mainly from film emulsion melting and the vinegar syndrome. We have devised the algorithm based on the observation that the affected areas did not lose their contents entirely. Rather, one of the film layers still preserves some of the original image structure. This artefact behaviour is exploited for both identifying and restoring these artefacts. The algorithm is validated by showing some results on real case examples.
