Abstract

We present in this paper a novel and effective system for removing blotches in old film sequences. In particular we propose a new very efficacious detection method: it is able to yield a high correct detection rate while minimizing, at the same time, the false alarm rate. Moreover, it is very efficient also in presence of slow motion, since it exploits both temporal and spatial features of the blotches. Adaptive Block Matching is used for the blotch correction step.
