Behavior Analysis: Detecting and Indexing Moving Objects for Behavior Analysis by Video and Audio Interpretation Alessia Saggese

In the last decades we have assisted to a growing need for security in many public environments. This consideration has led the proliferation of cameras and microphones, which represent a suitable solution for their relative low cost of maintenance, the possibility of installing them virtually everywhere and, finally, the capability of analyzing more complex events. The main limitation of this traditional audio-video surveillance systems lies in the so called psychological overcharge issue of the human operators responsible for security, that causes a decrease in their capabilities to analyze raw data flows from multiple sources of multimedia information. For the above mentioned reasons, in this book we propose an intelligent surveillance system able to provide images and video with a semantic interpretation, for trying to bridge the gap between their low-level representation in terms of pixels, and the high-level, natural language description that a human would give about them.
