| 摘 要： | 通过获取足迹标号图像,分别计算求得五趾和脚跟的质心坐标,得到脚趾与脚跟质心之间平均距离、五趾与脚跟质心之间夹角和五趾质心多边形等特征,并将这些特征与人体性别、胖瘦以及个体唯一性进行了统计分析。实验结果表明脚趾与脚跟质心之间平均距离能够较好的区分出人体性别,五趾与脚跟质心夹角对人体胖瘦、性别的分析有一定帮助,而五趾质心多边形可以作为立体赤足迹同一认定的依据之一。

| Abstract: | By acquiring the image of footprint with label,we com-pute the centers of mass of toes and heel respectively. Subse-quently,we can gain features, such as the average distance be-tween the centroid of toes and heel,the angle between toes andheel,and the polygon with centroid.And we analyse these fea-tures with gender, physique and uniqueness.The experimentsshow that the average distance could distinguish the gender verywell,the angle could help us analyse physique and gender,andthe polygon could be regarded as one of bases to identify barefootprint. |
