Figure 7From: Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique Frames 66, 70 and 77 of DanceB1 (top) with their reconstructions using JONDI (middle) and BTBR-F (bottom). Both systems perform well in removing blotches (shown in blue); however, JONDI could fail in removing blotches that lie near dark regions (box B). In addition, JONDI often misclassifies clean regions as corrupted. This could lead to severe reconstruction errors as shown in boxes A and C. On the other hand, BTBR-F classifies clean regions as uncorrupted, therefore disregard them from reconstruction.Back to article page
