Offering the first comprehensive analysis of touchless
fingerprint-recognition technologies, Touchless Fingerprint
Biometrics gives an overview of the state of the art and describes
relevant industrial applications. It also presents new techniques
to efficiently and effectively implement advanced solutions based
on touchless fingerprinting. The most accurate current biometric
technologies in touch-based fingerprint-recognition systems require
a relatively high level of user cooperation to acquire samples of
the concerned biometric trait. With the potential for reduced
constraints, reduced hardware costs, quicker acquisition time,
wider usability, and increased user acceptability, this book argues
for the potential superiority of touchless biometrics over
touch-based methods. The book considers current problems in
developing high-accuracy touchless recognition technology. It
discusses factors such as shadows, reflections, complex
backgrounds, distortions due to perspective effects, uncontrolled
finger placement, inconstant resolution of the ridge pattern, and
reconstruction and processing of three-dimensional models. The last
section suggests what future work can be done to increase accuracy
in touchless systems, such as intensive studies on extraction and
matching methods and three-dimensional analytical capabilities
within systems. In a world where usability and mobility have
increasing relevance, Touchless Fingerprint Biometrics demonstrates
that touchless technologies are also part of the future. A
presentation of the state of the art, it introduces you to the
field and its immediate future directions.

This book examines the context, motivation and current status of
biometric systems based on the palmprint, with a specific focus on
touchless and less-constrained systems. It covers new technologies
in this rapidly evolving field and is one of the first
comprehensive books on palmprint recognition systems. It discusses
the research literature and the most relevant industrial
applications of palmprint biometrics, including the low-cost
solutions based on webcams. The steps of biometric recognition are
described in detail, including acquisition setups, algorithms, and
evaluation procedures. Constraints and limitations of current
palmprint recognition systems are analyzed and discussed. The
authors also introduce innovative methods for touchless and
less-constrained palmprint recognition, with the aim to make
palmprint biometrics easier to use in practical, daily-life
applications, and overcome the typical constraints and limitations
described. Touchless Palmprint Recognition Systems targets
professionals and researchers working in biometrics, image
processing and three-dimensional reconstruction. Advanced-level
students studying biometrics and computer science will also find
this material valuable as a secondary text book or reference.
