由于人的静脉纹路完全不同，因此可以通过比较纹路来识别人。我们提出了比较静脉图像的认证系统，以实现低成本、高速、高精度的认证。认证设备由近红外光源和单色 CCD 组成，可产生皮下静脉的对比度增强图像。我们采用仅相位相关和模板匹配作为识别算法。我们测试了多种降噪滤波器、清晰度滤波器和直方图操作，以尽最大努力。因此，我们在该体系中获得了很高的认证率。
Since vein patterns of human are completely different from each other, it is possible to identify the person by comparing the patterns. We propose the certification system that compares vein images for low-cost, highspeed and high-precision certification. The equipment for authentication consists of a near infrared light source and a monochrome CCD to produce contrast-enhanced images of the subcutaneous veins. We adopted phase only correlation and template matching as a recognition algorithm. We tested several noise-reduction filters, sharpness filters and histogram manipulations for best effort. As a result, we obtained high certification ratio in this system.
