Developing a contactless palmprint authentication system by introducing a novel ROI extraction method ?
A novel unrestricted, contactless palmprint image acquisition device is developed. A novel model-based ROI extraction method, robust to the small errors is proposed. A contactless palmprint DB is constituted by collecting 1752 images from 145 subjects. The images in DB have pose, rotation, position variations and cluttered backgrounds. The results achieved by the proposed system are encouraging: 0.277% EER and 99.488% RR.
