| 摘 要： | 颅骨作为一个新的生物特征被提出并越来越引起研究者的注意,该特征的突出优点是不受表情的干扰和光线的约束.本文首先提取描述颅骨个体特征的边缘轮廓信息,然后对该边缘信息实现了多项式拟合,给出了颅骨轮廓的具体计算表达式,最后基于颅骨特征的解析表示给出了相应的识别判定准则.试验结果表明,该方法是有效可行的,适用于对活体或非活体进行身份识别.

| Abstract: | The prominent characteristics of skull biometrics have less affection with facial express and illumination while researchers pay attention to acquisition without contacting. In this paper firstly the feature curve edges are abstracted from the edge ,then the feature expressions are estimated and finally the recognition ruler is given and implemented. The experiment indicated that this approach was valid for not only ante mortem but also postmortem. |
