A simple example demonstrating the benefits of applying different speeds on different boundaries. In this case, an intensity weight of 0.7 was applied in all cases. Curvature terms with weights of 0.1 and 1.0 were applied to all objects in the “Small curvature” and “Large curvature” cases. In the variable curvature experiment, a curvature weight of 0.1 was applied to the red-blue boundary, while all other boundaries had a curvature weight of 1.0. This allowed the high spatial frequencies of the true object to be captured on one boundary, while simultaneously and correctly smoothing noise on another.
