Image processing techniques for improving vascular hand biometrics

Abstract

Since the beginning of hand vein biometrics, the approaches to this problem have been countless, making this modality suitable for commercial use in some countries. This paper shows some of them and tries to show which are the most common procedures in each of the main stages of these systems. We will be able to see that the same database usage is not common along the literature, being the main problem when evaluating the performance of a new system.
