Curvature approximation from parabolic sectors
Gual-Arnau, Ximo; Ibáñez Gual, Maria Victoria; Monterde, Juan International Society for Stereology (2017)We propose an invariant three-point curvature approximation for plane curves based on the arc of a parabolic sector, and we analyze how closely this approximation is to the true curvature of the curve. We compare our results ...
