查询词典 fingerprint

A new concept on the continuously distributed directional image/field and the method to compute it in the fingerprint images are proposed,which exhibits not only good continuity,well gradualness,and excellent robustness to the noises,but very high precision,as well.

本文提出了指纹连续分布方向图的概念及其算法，连续分布方向图具有很好的连续性、渐变性、抗噪性和较高的精确度；对经典的PoincaréIndex计算公式和指纹奇异点检测算法进行了改进，改进后的PoincaréIndex不仅能精确表示向量场的旋转角度，而且还能精确表示向量场的旋转方向，能够在像素级水平精确定位指纹奇异点(core点和delta点)。

Then, the minutiae sets are aligned globally through coordinate transform, and the alignment parameters are optimized by using affine transform and least square method. Finally, minutiae matching and directional field matching are respectively achieved based on the minutiae alignment, and the two matching scores are fused into a single to obtain a more reasonable result. Experimental results show that this method contributes to ensure the accuracy of fingerprint identification as well as possesses the real-time performance.

该算法首先利用脊线信息快速确定满足局部匹配要求的细节点对，在此基础上进一步通过全局坐标变换完成细节点的全局配准，并采用仿射变换模型通过最小二乘估计对配准参数进行优化，然后在配准的基础上分别进行细节点匹配和方向场匹配，最后对两种匹配分值进行融合，以取得较合理的匹配结果。
