From: Robust and Accurate Curvature Estimation Using Adaptive Line Integrals
(a) The closed curve
, (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 a dashed blue line denotes the true curvature.
