This book describes a range of new biometric technologies, such as
high-resolution fingerprint, finger-knuckle-print, multi-spectral
backhand, 3D fingerprint, tongueprint, 3D ear, and multi-spectral iris
technologies. Further, it introduces readers to efficient feature
extraction, matching and fusion algorithms, in addition to developing
potential systems of its own. These advanced biometric technologies and
methods are divided as follows: 1. High-Resolution Fingerprint
Recognition; 2. Finger-Knuckle-Print Verification; 3. Other Hand-Based
Biometrics; and 4. New Head-Based Biometrics.
Traditional biometric technologies, such as fingerprint, face, iris, and
palmprint, have been extensively studied and addressed in many research
books. However, all of these technologies have their own advantages and
disadvantages, and there is no single type of biometric technology that
can be used for all applications. Many new biometric technologies have
been developed in recent years, especia
lly in response to new applications. The contributions gathered here
focus on how to develop a new biometric technology based on the
requirements of essential applications, and how to design efficient
algorithms that yield better performance.
