曲率是二维(2D)形状分析中经常使用的属性，可以直接使用，也可以用于派生特征，如拐角或凸弧和凹弧。本文介绍了遵循微分几何方法的曲率估计器。在这些估计器中使用数字-直线段近似(如数字几何所知)。对多重网格实验的结果进行了评估，并对几种曲率估计器的性能进行了比较分析
Curvature is a frequently used property in two-dimensional (2D) shape analysis, directly or for derived features such as corners or convex and concave arcs. This paper presents curvature estimators which follow approaches in differential geometry. Digital-straight segment approximation (as known from digital geometry) is used in those estimators. Results of multigrid experiments are evaluated leading to a comparative performance analysis of several curvature estimators
