Effect of polarization filters on hand vein sample image quality

Abstract

This is work about using (polarization) filters in hand-vein biometric recognition. Experiments clearly demonstrate that the respective application of linear polarization, circular polarization, and band pass filters on the capturing lens improve hand-vein sample image quality across a considerable range of specific vascular image quality metrics. In case the illumination source is additionally equipped with a linear polarization filter (in relative perpendicular direction), further quality improvement could not be demonstrated.
