| 摘 要： | 针对通常的指纹识别算法都不支持指纹的旋转和偏移的问题 ,文中首先提出一个在二维平面上点与点之间的距离与平面的旋转和平移无关的数学模型。然后在分析指纹特征点的基础上提出一个基于指纹结构特征的比对算法 ,该算法主要是利用特征点之间的距离、类型和跨越纹线等结构信息来进行比对。最后用实验证明这一算法的可行性

| Abstract: | Aiming at the problem that general fingerprint image recognition algorithm gave no support to the rotation and the displacement of the fingerprint image,the mathematic model is proposed in which the distance between two points in a plane is independent of the rotation or displacement of this plane.Then,according to the analysis of the structural feature minutia of the special points,the comparision algorithm of the structural features of the special points is proposed.In this algorithm,the distance between special points,the types,and the numbers lines spanned by the special points are compared.A lot of experiments have been made,and the feasibility of this method is demonstrated. |
