This is the last left-field column of 2008 and I would like to take this opportunity to wish everyone a happy New Year and a happy holidays, looking forward to meeting again in 2009 with a lot of interesting left-field articles! A new workshop grabbed my attention in the ACM DL - "Proceeding of the 1st ACM workshop on Analysis and retrieval of events/actions and workflows in video streams AREA '08". I think all the papers in this proceeding would be interesting to people working on video accessibility, however I wanted to highlight one which is called "Event detection for video surveillance using an expert system". This paper presents an expert system that encodes seven rules to represent and detect seven predefined events. These events represent dangerous situations in a subway station such as someone being trapped by the door of a moving train. I wonder if such systems would be used to inform blind users about the dangerous situations in the environment.
Event detection for video surveillance using an expert systemVideo Surveillance is in the center of research due to high importance of safety and security issues. Usually, humans have to monitor an area and often they have to do this for 24 hours a day. Thus, it would be desirable to have automatic surveillance systems that support this job automatically. The system described in this paper is such an automatic surveillance system that has been developed to detect several dangerous situations in a subway station. This paper discusses the high-level module of the system. Herein, an expert system is used to detect events.Full Paper: http://doi.acm.org/10.1145/1463542.1463551
