摘要
文章对传统的指纹识别算法进行了分析、总结,提出了一种新的基于指纹方向图的指纹识别算法。同传统的指纹识别算法相比较,其优点为抗扰性强,识别率高。实验证明,文章提出的指纹识别算法能够克服一定范围内的指纹旋转及平移因素的影响,对于残缺或模糊的指纹图像也有较好的识别效果。
In the paper, an automatic fingerprint identification system is introdliced. Through experiments, our classification method is proved to have a relatively high rate of fingerprint recognition and a strong ability to resist image noises. In addition, it is also proved to be relatively high effective in recognizing damaged or blurry fingerprint images. The system is relstively high valhable in practice.
