Book Description
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.

Book Description
The development of technologies for the identi?cation of individuals has driven the interest and curiosity of many people. Spearheaded and inspired by the Bertillon coding system for the classi?cation of humans based on physical measurements, scientists and engineers have been trying to invent new devices and classi?cation systems to capture the human identity from its body measurements. One of the main limitations of the precursors of today’s biometrics, which is still present in the vast majority of the existing biometric systems, has been the need to keep the device in close contact with the subject to capture the biometric measurements. This clearly limits the applicability and convenience of biometric systems. This book presents an important step in addressing this limitation by describing a number of methodologies to capture meaningful biometric information from a distance. Most materials covered in this book have been presented at the International Summer School on Biometrics which is held every year in Alghero, Italy and which has become a ?agship activity of the IAPR Technical Committee on Biometrics (IAPR TC4). The last four chapters of the book are derived from some of the best p- sentations by the participating students of the school. The educational value of this book is also highlighted by the number of proposed exercises and questions which will help the reader to better understand the proposed topics.

Book Description
Automatic personal authentication using biometric information is becoming more essential in applications of public security, access control, forensics, banking, etc. Many kinds of biometric authentication techniques have been developed based on different biometric characteristics. However, most of the physical biometric recognition techniques are based on two dimensional (2D) images, despite the fact that human characteristics are three dimensional (3D) surfaces. Recently, 3D techniques have been applied to biometric applications such as 3D face, 3D palmprint, 3D fingerprint, and 3D ear recognition. This book introduces four typical 3D imaging methods, and presents some case studies in the field of 3D biometrics. This book also includes many efficient 3D feature extraction, matching, and fusion algorithms. These 3D imaging methods and their applications are given as follows: - Single view imaging with line structured-light: 3D ear identification - Single view imaging with multi-line structured-light: 3D palmprint authentication - Single view imaging using only 3D camera: 3D hand verification - Multi-view imaging: 3D fingerprint recognition 3D Biometrics: Systems and Applications is a comprehensive introduction to both theoretical issues and practical implementation in 3D biometric authentication. It will serve as a textbook or as a useful reference for graduate students and researchers in the fields of computer science, electrical engineering, systems science, and information technology. Researchers and practitioners in industry and R&D laboratories working on security system design, biometrics, immigration, law enforcement, control, and pattern recognition will also find much of interest in this book.

Book Description
The use of biometrics to identify individuals has become an important component of efforts to ensure U.S. national security, and has also grown rapidly. Biometrics are, for example, an integral part of the United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program. To address contagion and speed issues, DHS S&T commissioned and funded a project to research technologies that could be used to acquire fingerprints without physical contact. Overall the contactless scanner took longer to acquire the prints, acquired fewer prints under the no instruction and video instructional conditions, and was preferred less than the contact scanner.

Book Description
This document details efforts undertaken by the National Institute of Standards and Technology (NIST) to develop measurements and a protocol for the evaluation of contactless (touchless) fingerprint acquisition devices. Contactless fingerprint capture differs fundamentally from legacy contact fingerprinting methods, and poses novel problems for image quality evaluation and challenges relative to interoperability with contact fingerprints that populate large repositories maintained by law enforcement and Federal Government organizations. For contact acquisition, the fingerprint impression is a first-order transfer of the 3D friction ridge structure to the recording surface. The third dimension of the curved finger surface is effectively removed by pressure against the planar recording surface. The 3D topography of the ridges and furrows are transferred with low ambiguity to the recording surface as dark ridges (points of contact) and lighter furrows (lesser or no contact). Contactless images by comparison, in most cases, are third-order renderings of an original photographic representation, itself a 2D optical projection of the 3D structure of the finger. The appearance of this projection is subject to variability as low- or moderately-controlled lighting interacts with the 3D geometry of the finger, the friction ridge structure superimposed on the finger, and the geometry of the presentation of the finger to the contactless device. The photograph must then be subjected to various image processing methods to infer the ridge structure for rendering as a fingerprint similar in appearance to legacy contact captures. The rendering process is the source of numerous errors relative to contact captures. Despite problems with image quality, this early study finds contactless fingerprints of the devices examined to be usable in some applications, with qualifications, including one- to-many matching against small databases.
