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.
