As biometric-based identification and identity authentication becomes increasingly widespread in their deployment, it becomes important to consider issues relating to reliability, usability and inclusion. Factors which are particularly important in this context are the relationship between the nature of the measurements extracted from a particular biometric modality, the age of the sample donor, and the effect which age has on physiological and behavioral characteristics invoked in a biometric transaction. Topics include: * review of ageing and biometrics* social factors in ageing and their...

Containing a wealth of real world advice and written from an operational perspective, "Practical Biometrics" examines the many issues raised by the application of biometric technologies to practical situations, with specific regard to wide scale public applications. It acts as a practical guide to implementation, identifying the associated issues around:

* Scalability in applications featuring biometric verification techniques

* Interoperability, both from a technical and operational perspective

* Ethnicity and the associated implications for...

Biometrics such as fingerprint, face, gait, iris, voice and signature, recognizes one's identity using his/her physiological or behavioral characteristics. Among these biometric signs, fingerprint has been researched the longest period of time, and shows the most promising future in real-world applications. However, because of the complex distortions among the different impressions of the same finger, fingerprint recognition is still a challenging problem.

Computational Algorithms for Fingerprint Recognition presents an entire range of novel computational...

The term speech processing refers to the scientific discipline concerned with the analysis and processing of speech signals for getting the best benefit in various practical scenarios. These different practical scenarios correspond to a large variety of applications of speech processing research. Examples of some applications include enhancement, coding, synthesis, recognition and speaker recognition. A very rapid growth, particularly during the past ten years, has resulted due to the efforts of many leading scientists. The ideal aim is to develop algorithms for a certain task that maximize...

This book is the Proceedings of the First International Symposium for Science on Form. The Symposium was held on November 26 through 30, 1985 at the University of Tsukuba, Japan. It was organized by The Society for Science on Form, J:: . pan, and sponsored by the Foundation for Advancement of International Science (F AIS). The purpose of the Symposium was to discuss interdisciplinal science aspects of form. "Form," to exhibit its tremendous characters, depends on the material and the changes. But, it is the form that appears evident at once and endures. Form is absorbed from every field as...

Practical OpenCV is a hands-on project book that shows you how to get the best results from OpenCV, the open-source computer vision library.

Computer vision is key to technologies like object recognition, shape detection, and depth estimation. OpenCV is an open-source library with over 2500 algorithms that you can use to do all of these, as well as track moving objects, extract 3D models, and overlay augmented reality. It's used by major companies like Google (in its autonomous car), Intel, and Sony; and it is the backbone of the Robot Operating System's computer vision...

A useful guide to optical discs for the forensic professional or anyone that deals with optical media. Focus is on specifics that will insure proper handling and processing of discs to assure against loss of data and potential evidence. The author has been working with optical media since 1994 and is the author of a number of software products for writing optical media, recovering data from optical media and forensic examination of optical media. This is the second edition of this book and contains updated information and more focus on Blu-ray media.

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...

The main objective of the dissertation is to present work describing theoretical studies of planar structures with erbium doped regions and characterization of erbium doped particles. Numerical models of erbium doped Al2O3 were formulated, taking into account the up-conversion from the metastable Er3+ levels and the cross-relaxation process as a mechanism of energy transfer between Er3+ ions. The influence of amplified spontaneous emission (ASE) is also fully considered in the numerical model. The first part of this research investigates the effects of design geometries and nonlinear losses...
