摘要：

Blotch detection and removal is an important issue for archive film restoration. In this work, a two-stage Simplified Ranked Order Difference (SROD) detector that takes local motion changes into consideration has been proposed to increase blotch detection performance. Furthermore a novel pixel-based correction method that determines the new values of blotched pixels from spatio-temporal correlation considering edge information is developed. Experimental results show that the proposed approaches give successful detection and correction performances and outperform previously proposed techniques. (c) 2007 Elsevier GmbH.
