Abstract

In this paper, we consider the problem of detecting and removing blue scratches from digital image sequences. In particular, we propose a detection method and a removal method that strongly rely on the specific features of such scratches. Evaluation of the proposed methods, in terms of both accuracy and performance timings, and numerical experiments on real images are reported.
