Robust Palm-Vein Recognition Using the MMD Filter: Improving SIFT-Based Feature Matching
Kaveen Perera, Fouad Khelifi, Ammar Belatreche
A major challenge with palm vein images is that slight movements of the fingers and thumb, or variations in hand posture, can stretch the skin in different areas and alter the vein…
