Figure 10From: Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique Corrupted image, IR scan, dirt opacity obtained using the derived IR/corruption relation, and corresponding reconstruction. They correspond to the images from left to right. The corruption opacity field is inverted for the simplicity of comparison with the IR. As shown, the reconstruction successfully recovers the underlying original data; however, it fails to remove highly opaque corruptions (last row).Back to article page
