                         relies on geometric properties of curves, particularly their 
                         curvature. Several methods have been proposed to estimate the 
                         curvature of a planar curve, most of them for curves in digital 
                         spaces. This work proposes a new method for curvature estimation 
                         based on weighted least square fitting and local arc­length 
                         approximation. Convergence analysis of this method and noise 
                         impact on the estimator accuracy are given. Numerical robustness 
                         issues are addressed with practical solutions. The implementation 
                         of the method is compared to other curvature estimation methods.",
