Capturing Hand or Wrist Vein Images for Biometric Authentication Using Low-Cost Devices
ABSTRACT
Biometric recognition is becoming more and more important owing to the need
for authentication in several fields like security or convenience applications. In
this paper, a new imaging capturing technique based on near-infrared illumination
to acquire wrist vein pattern images for biometric purposes is analysed. Experi-
ments and tests involving data acquisition in different illumination conditions are
described using a population of 30 test subjects. Comparison and analysis of the
data collected with other techniques show that this hardware method is suitable to
obtain high quality wrist veins images that can be used in the feature extraction
phase to extract the wrist vein patterns for biometric recognition.
