| 摘 要： | 指纹匹配算法是指纹准确识别的关键算法之一。在常见的三角形匹配算法的基础上，提出了一种改进的基于脊线相似性的三角形匹配算法。在对指纹预处理图像进行八邻域特征提取后，利用脊线的相似性选择特征点进行三角形匹配，在一定程度上减少了相似三角形的个数，提高了匹配速度与精度。实验证明，本算法取得了良好的识别效果。

| Abstract: | Fingerprint matching is one of the key algorithms of fingerprint identification.A new improving triangle matching algorithm is put forward to carry out matching based on ridge comparability.After abstracting the characteristics at eight neighborhoods and utilizing the similarity of ridge to select the characteristics,this method reduces the number of similar triangles to some extent and improves the speed and precision of matching.The simulation results show that the methods in this paper achieve favorable ... |
