| 摘 要： | 在实验上建立了一套基于联合变换相关的１ｆ光电混合实时指纹识别系统，用棱镜和ＣＣＤ摄像机结合实现指纹的实时采集，提出了用二次微分边缘提取算法对指纹进行预处理，用监视器上亮度和对比度调节来实现联合变换功率谱的视觉二值化。

A New Method for Real-Time Hybrid Fingerprint Identification |
| |
| Abstract: | A real-time optical/digital hybrid system for fingerprint identification based on the 1-f joint transform correlation is developed. The fingerprint is read by using the total internal reflection property of a prism and is pre-processed by two-order differenciation algorithm. The joint transform power spectrum can be binazed visually by adjusting the Monitor. This system is demostrated, and the experimental results show that it performs well. |
