Presentation attack on the face recognition systems is well studied in the biometrics community resulting in various techniques for detecting the attacks. A low-cost presentation attack (e.g. print attacks) on face recognition systems has been demonstrated for systems operating in visible, multispectral (visible and near infrared spectrum) and extended multispectral (more than two spectral bands spanning...
Dry or wet fingers have an impact on biometric performance and the measurement of skin characteristics is important for actionable quality. We collected a ground truth fingerprint skin moisture dataset containing 6600 samples from 33 subjects using 5 optical sensors, two claimed to work well in extreme skin moisture conditions. Controlling conditions by applying cream, alcohol and water we performed...
Enhancement of image quality is a key problem for automated fingerprint recognition systems, especially for minutiae-based analysis. In this paper, five enhancement algorithms, including three popular enhancement algorithms and two combined algorithms, were reviewed. The FVC2000 DB1 B was chosen as the testing database. An algorithm evaluating platform based on minutiae comparison was implemented...
