The past decades have seen significant improvements in 3D imaging where the related techniques and technologies have advanced to a mature state. These exciting developments have sparked increasing interest in industry and academia in the challenges and opportunities afforded by 3D sensing. As a consequence, the emerging area of safety and security related imaging incorporates these important new technologies beyond the limitations of 2D image processing. This is the first book that covers the current state-of-the-art in 3D imaging for safety and security. Topics addressed in this book include 3D imaging related to biometrics, face recognition, surveillance, safety inspection and robotic planning for physical security analysis and public safety. The book presents thoroughly revised versions of lectures given by leading researchers during the 'Workshop on Advanced 3D Imaging for Safety and Security' in conjunction with the International Conference on Computer Vision and Pattern Recognition CVPR 2005 on June 25, 2005 in San Diego, USA.
