英文摘要： The emergence and development of video-sharing sites, P2P, microblog, podcasting, mobile WAP sites and 3GP sites facilitate the dissemination of sensitive videos, which poses a major threat to national security, social stability, and physical and mental health of teenagers. With the increasing demands for network content security, this project is intended to explore some important frontier problems of web sensitive video recognition. For recognizing specific types of sensitive videos, this project emphasizes on two aspects: pornographic video recognition based on probability fusion from multi-modals and multi-clues; violent video recognition via incorporating contextual information from images, motion analysis, audio intensity, emotional expression, etc. For customizable instance- driven sensitive video recognition, this project focuses on sensitive video recognition based on specific target attribute learning and that based on multi-feature semantic association copy detection. Eventually, a web sensitive video recognition system shall be completed. The project will result in several invention patents and other independent intellectual property rights. Meanwhile, a series of high-quality papers shall be published in international top journals or major international academic conferences. The objective of this project is to bring the research of our country in this field to reach the international advanced level and enhance the overall capacity of our country for web sensitive video surveillance.
