1. Improving fingerprint biometrics by local symmetry and fusion
Abstract : Fingerprint recognition and biometrics in general have been significantly gaining attention within the last years, not least due to the biometric passport that has been introduced all over Europe and the American immigration management system US-VISIT. The tasks of fingerprint recognition can be broken down to smaller entities, i.e. READ MORE

2. Lip-motion and speech biometrics in person recognition
Abstract : Biometric identification techniques are frequently used to improve security, e.g. in financial transactions, computer networks and secure critical locations. The purpose of biometric authentication systems is to verify an individual by her biological characteristics including those generating characterisitic behaviour. READ MORE

3. Lip-motion biometrics for audio-visual identity recognition
Abstract : Biometric recognition systems have been established as powerful security tools to prevent unknown users from entering high risk systems and areas. They are increasingly being utilized in surveillance and access management (city centers, banks, etc.) by using individuals' physical or biological characteristics. READ MORE

4. Compact orientation and frequency estimation with applications in biometrics : Biometrics on the orientation express
Abstract : Automatic feature extraction still remains a relevant image and signal processing problem even tough both the field and technologies are developing rapidly. Images of low quality, where it is extremely difficult to reliably process image information automatically, are of special interest. READ MORE

5. Evidence for "liveness" in face biometrics
Abstract : Aliveness or "liveness" detection is a novel but crucial topic in biometrics. In this study we will investigate it for face biometrics. The problem is given by the real-time requirements of such a system to be able to avert advanced spoofing attempts, e.g. READ MORE
