This volume is an initiative undertaken by the IEEE ComputationalIntelligence Society's Task Force on Security, Surveillance and Defense to consolidateand disseminate the role of CI techniques in the design, development anddeployment of security and defense solutions. Applications range from thedetection of buried explosive hazards in a battlefield to the control ofunmanned underwater vehicles, the delivery of superior video analytics forprotecting critical infrastructures or the development of stronger intrusiondetection systems and the design of military surveillance networks. Defensescientists, industry experts, academicians and practitioners alike will allbenefit from the wide spectrum of successful applications compiled in thisvolume. Senior undergraduate or graduate students may also discover unchartedterritory for their own research endeavors.
