Abstract:Finger vein recognition is emerging as a new form of biometrics. There are multiple devices that are commercially available which claim to have an outstanding performance. However, little research is done into finger vein scanners. The SCS group designed their own finger vein reader, but it needed a redesign. This paper focuses on the important aspects for a redesign like: camera, IR pass filter and illumination method. Also a method is proposed that evaluates the image quality of a vascular pattern image. This is done by looking at the contrast between finger tissue and vein, the homogeneity of the image and the overexposure of the finger contours. The evaluation method is used to compare the performance of the old setup with the new setup. In this comparison the new device performed better, but there are many aspects that still need to be investigated before such statements can be made.
