Abstract

In this chapter, our goal is to remove blotch noises as well as straight line scratches commonly seen in old film movies using digital image processing techniques. We proposed an adaptive blotch detection method based on our blotches characteristic analysis, where we calculate the size of each connected region using Connected Component methods to distinguish blotches and non-blotches, as a result, the proposed method can accurately mark the blotches noises. We also proposed a method to avoid misclassifying of small objects as blotches using and improving the accuracy of marked blotches. We adopt and improve Inpainting algorithm to repair the blotches noise. Inpainting algorithm is highly dependent on the order in which the filling proceeds; we also extend this approach to color images. In addition, we proposed criterion for performance evaluation of the proposed method.
