| 摘 要： | 提出了一种新的指纹细节点匹配算法。该算法首先基于细节点方向分布特性将指纹在旋转方向上对齐，减少了大量的旋转操作，然后利用大小变化的界限盒判定细节点之间的对应关系。该算法不受指纹之间旋转变形、平移变换和非线性变形的影响，也不受细节点提取误差的影响。实验结果表明该算法不仅处理速度较快，而且具有令人满意的精度。

| Abstract: | A new fingerprints matching method is presented. Firstly, possible rotational difference between input fingerprint and model fingerprint is estimated. Then, Minutiae matching is completed by using bounding box with non-fixed size. The method is robust to the rotation, translation and nonlinear deformations between fingerprints. Experimental results show that the method is last and its accuracy is acceptable. |
