From: Robust and Accurate Curvature Estimation Using Adaptive Line Integrals
Trial-to-trial variability in curvature estimates. The data consist of 10 trials. (a) The closed curves 
with additive Gaussian noise, (b) curvature estimate obtained by derivative of tangent, (c) curvature estimate obtained by Calabi et al.'s algorithm, (d) curvature estimate obtained by Taubin's algorithm, (e) curvature estimate obtained by line integrals, and (f) curvature estimate obtained by line integrals with adaptive radius. Notice that these figures have different ranges in vertical coordinate because some methods yield noisy results. The true curvature is denoted by a dashed blue line.
