Blotches are one of the most common film degradations that must be detected and corrected in the process of film restoration. In this work we will address the problem of blotch detection in the context of digital film restoration. Although there are several methods for blotch detection, in the literature their evaluation is usually subjective. In this work we propose a new method for blotch detection and an objective methodology to evaluate its performance. We show that the proposed method outperforms other existing methods while using this objective metric.
