This interdisciplinary volume presents a detailed overview of the latest advances and challenges remaining in the field of adaptive biometric systems. A broad range of techniques are provided from an international selection of pre-eminent authorities, collected together under a unified taxonomy and designed to be applicable to any pattern recognition system. Features: presents a thorough introduction to the concept of adaptive biometric systems; reviews systems for adaptive face recognition that perform self-updating of facial models using operational (unlabeled) data; describes a novel semi-supervised training strategy known as fusion-based co-training; examines the characterization and recognition of human gestures in videos; discusses a selection of learning techniques that can be applied to build an adaptive biometric system; investigates procedures for handling temporal variance in facial biometrics due to aging; proposes a score-level fusion scheme for an adaptive multimodal biometric system.

The first book dedicated to the emerging field of adaptive biometric systems Describes the schemes and learning mechanisms involved in biometric system adaptation, and provides insight into the levels at which the process of adaptation can be performed Presents interdisciplinary coverage, bridging areas of computational intelligence, pattern recognition, machine learning, and signal processing Includes supplementary material: sn.pub/extras
