This paper presents an automatic scratch detection and removal approach for archive film sequences. The proposed detector mainly exploits temporal coherency of candidate scratch positions, which are obtained using an automatic scratch detection method proposed in the literature. In the restoration stage, both spatial and temporal information are employed. The proposed edge priority based scratch removal algorithm successfully removes scratch effects from archive film sequences
