Intelligent visual surveillance has emerged as a promising research area in computer vision. Meanwhile, intelligent visual surveillance has wide application perspective, and provides strong supports for public security. To promote the adoption of visual surveillance, previous three editions of Chinese Conference on Intelligent Visual Surveillance have been held in 2002, 2003 and 2011 successfully. In recent years, intelligent visual surveillance has achieved greater advancement. New solutions and techniques are being discovered in an endless stream. Furthermore, as more “Safe Cities” and “Smart Cities” have been constructed, the issues of public security become much more important. And many surveillance companies are paying more attention to “intelligent techniques” in visual surveillance systems. In order to respond to the voice of “strengthen communication, enhance understanding and improve cooperation” between academic community and industrial communities, the 4th Chinese Conference on Intelligent Visual Surveillance is about to be held on 19th October 2016.
