The Prevention of Vandalism in Metro Stations

A neural network-based image processing system for detection of vandal acts in unmanned railway environments

“…metros and other means of local transport. It is estimated that about 150,000 Euros must be spent by the Belgian metro management agency of Brussels only for removing graffiti from walls [1]. It is clear that video-surveillance systems are an upcoming business for these applications.…”

Use of neural networks for behaviour understanding in railway transport monitoring applications

“…These last years have been characterized by increasing losses in terms of money and prestige for means of public transport caused by a subjective and objective lack of security [1]. The reasons for these problems can be mainly found in the social development.…”

“…A first prototype of video-surveillance system for detection of vandal acts in metro stations was developed during the European ESPRIT AVS-PV (Advanced Video-Surveillance -Prevention of Vandalism) project [2]. The project, ended in 1998, led to the implementation of an image processing system able at detecting 1 Excited behavior of a person, whether acting alone or in a small gang. The implemented system was based on the detection and tracking of some mobile areas in the monitored scene (i.e.…”
