This is the first book to bridge the data processing and intelligent reasoning methods for the creation of human-centered, ambient intelligence systems. This book will be an ideal reference for researchers universities, R & D engineers, computer engineers, and graduate students working in signal, speech and video processing, multi-modal interfaces, human-computer interaction and ambient intelligence applications. Hamid Aghajan is Professor of Electrical Engineering (consulting) at Stanford University, USA. He is Editor-in-Chief of "Journal of Ambient Intelligence and Smart Environments", has led the ACM / IEEE ICDSC 2008, and workshops held / session / tutorial at ECCV, ACM MM, FG, ECAI, ICASSP, CVPR. Juan Carlos Augusto is a lecturer at the University of Ulster, UK. He is Editor-in-Chief of Book Series on "Ambient Intelligence and Smart Environments" and "Journal of Ambient Intelligence and Smart Environments". He is a member of Isca (International Speech Communication Association), SEPLN (Spanish Society for Natural Language Processing) and AIPO (Spanish Society in HCI). Integrating techniques and computational methods that are essential for designing and implementing a highly effective system of ambient intelligence Contains contributions from the world's leading experts in academia and industry Give the full picture, paradigm principles and applications of human-centric ambient intelligence systems
