| Abstract: | Finger-vein images are a powerful biometric, which could replace fingerprint images in the future. In this paper, a method is proposed for capturing uniformly lit finger-vein images, which does not make use of a controllable light source. The method implies taking several images with differing shutter times, and combining them into a single image in which the finger is lit uniformly. The total capture time of the images taken using the proposed method is decreased drastically compared to methods using a controllable light source, and is independent of the imaged finger. The image quality using the proposed method is mostly improved, but still dependent on the imaged finger. A modification is proposed to set the appropriate shutter times for different finger types. The main question to be answered is whether finger-vein imaging devices can be built without a controllable light source which can use the method without decreasing image quality. |
