Longitudinal Finger Rotation - Problems and Effects in Finger-Vein Recognition
Abstract
Finger-vein scanners or vein-based biometrics in general are becoming more and more
popular. Commercial off-the-shelf finger-vein scanners usually capture only one finger from the
palmar side using transillumination. Most scanners have a contact area and a finger-shaped support
where the finger has to be placed onto in order to prevent misplacements of the finger including
shifts, planar rotation and tilts. However, this is not able to prevent rotation of the finger along its
longitudinal axis (also called non-planar finger rotation). This kind of finger rotation poses a severe
problem in finger-vein recognition as the resulting vein image may represent entirely different
patterns due to the perspective projection. We evaluated the robustness of several finger-vein recognition
schemes against longitudinal finger rotation. Therefore, we established a finger-vein data set
exhibiting longitudinal finger rotation in steps of 1° covering a range of 90°. Our experimental
results confirm that the performance of most of the simple recognition schemes rapidly decreases
for more than 10° of rotation, while more advanced schemes are able to handle up to 30°.
