应用Gabor滤波的指纹识别算法的研究和实现

提出了一种基于Gabor滤波提取指纹全局及局部特征的识别算法。目前广泛使用的基于细节点的算法识别性能较高，但由于需要前期预处理，增加了系统开销。另一方面，传统的基于结构特征的算法速度较快，然而对偏转指纹的识别性能较差。针对以上不足，利用滤波器定位参考点，并将以参考点为中心的特征提取区域划分为16方向的扇区，然后通过8方向滤波分别提取原始图像和旋转后图像的特征。在FVC2004指纹库上的对比实验证明，该算法同时具备了较好的运行效率和识别性能。

Development and implementation of Gabor filterbank-based fingerprint recognition algorithm

This paper proposes a novel fingerprint recognition algorithm based on Gabor filterbank to extract both global and local features of the fingerprints.At present,the widely used minutiae-based algorithm performs well on recognition while the preprocessing is time-consuming.On the other hand,the traditional structure-based algorithm is highly efficient but performs poorly on rotated pictures.The proposed approach uses filters to locate the core point,then tessellates the feature region centered at the referen...
