Radiation optimization and image processing algorithms in the identi- fication of hand vein patterns
ABSTRACT
Vein pattern recognition is one of the newest biometric techniques researched
today. While the concept behind the method is simple, there are various challenges
to be found throughout the design and implementation of a vein-scanning device
concerning the lighting system and the image processing algorithms. To achieve low
scanning errors, the acquired image should be almost noiseless and the algorithms
should detect the vein pattern in various conditions. Many implementations of
this method are now in a commercial phase and there is a great need for low cost
systems that can detect human veins with minimum computational requirements.
