IET's 4th International Conference on Imaging for Crime Detection and Prevention (ICDP-2011) 3rd-4th November 2011, Kingston University, London, UK Full Programme now ready. Early bird registration by 14th October. This conference follows the successful IDSS (Intelligent Distributed Surveillance Systems) events held in 2003 and 2004 and ICDP 2005, 2006 and 2009, to bring together researchers, industry, end-users, law-enforcing agencies and citizens groups to share experiences and explore areas where additional research, development and better working practices are needed, identify possible collaboration and consider the societal impact of such technologies. The 4th International Conference on Imaging for Crime Detection and Prevention (ICDP-11) aims to create an important networking forum in which participants can discuss the present and future of image-based technologies for crime detection and prevention. ICDP (and its predecessor IDSS) has traditionally been a special meeting point of different disciplines (computer science, social science, engineering, management, etc.) and an opportunity for a wide range of stakeholders to discuss the many different aspects of the application of imaging technologies in this socially crucial domain. http://www,icdp-conf.org
