| 摘 要： | 通过建立校准坐标系,对足迹特征点进行了统一的标注和基于计算几何学的精确测量,以实现赤足迹的自动定量分析.除了常见的几何测量（如距离和角度）外,提出了一种平均曲率能量的测量方法来描述边界曲线特征.运用方差分析理论,讨论了特征参数的个体差异性和同一稳定性,为足迹识别的特征选择提供了参考依据.

| Abstract: | An automatic quantitative analysis on the shape of barefoot impressions is performed by setting up an aligned coordinate system for each footprint and locating uniform landmarks for it, and precise shape measurements are provided for barefoot impressions using computational geometry method. Besides common geometric measurements such as distances and angles, a new measurement of average curvature energy defined for boundary curve segment is included in the set to describe curve feature. Distinguishability and stability of each feature parameter extracted form the footprint outlines in this study are analyzed based on variance theory as a reference for feature selection. |
