Video-based log generation for security systems in indoor surveillance scenarios
In the EU FP7-SEC-2012-1-313034 project SAWSOC (Situation AWare Security Operations Center) the objective is to achieve "the convergence of physical and logical security technologies, particularly improving correlation techniques across existing technology silos (video surveillance, access control, network monitoring, etc.)". In this paper two use cases developed in SAWSOC are presented in the perspective of video-based log generation. The first is a critical infrastructure where we log visual observable occurrences in a critical server room. The second is a soccer stadium environment where we log the patrol path of guards and ensure the correct handling of each checkpoint of their patrol path. Our approach consists of several generic computer vision modules and spatio-temporal data fusion using scene dependent knowledge. Each component of its own does not allow to make any statements about the current situation in the observed area. Instead, the sum of all components has to be considered.
