摘要

曲率是二维(2D)形状分析中经常使用的属性，直接或派生的特征，如角或凹凸弧。本文提出了遵循微分几何方法的曲率估计。在这些估计中使用了数字直段近似(从数字几何中已知)。对多网格实验结果进行了评价，并对几种曲率估计器的性能进行了比较分析

A Comparative Study on 2D Curvature Estimators

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
