Is White Light the Best Illumination for Palmprint Recognition?

摘要: Palmprint as a new biometric has received great research attention in the past decades. It owns many merits, such robustness, low cost, user friendliness, and high accuracy. Most of current palmprint recognition systems use an active light to acquire clear images. Thus, source is key component system capture enough discriminant information for recognition. To best our knowledge, white most widely used source. However, little work been done on investigating whether illumination In this study, we empirically compared accuracy using other six different color lights. The experiments large database show that not optimal This finding will be useful future design.
