Figure 9From: Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique IR values vs. corruption opacities α for the dance sequence. The red bars denote 1 standard deviation of α. Both y = a.x2 + b.x + c and y = γ.e x p(λ x) + k produce a good fit of the IR/corruption opacity relation. Results for only one sequence are shown here in the interest of brevity.Back to article page
