Audio event detection and localisation for directing video surveillance - a survey of potential techniques
J. Rex · 2011
Hearing is often a vital adjunct to vision for situational awareness. This article discusses how automatic techniques for audio event detection and localisation can bring major benefits when incorporated in video surveillance systems. There is an overview of the key technological components, with a particular focus on microphone array techniques for sound source localisation, and how techniques originally developed for voice communications can be adapted to surveillance applications.
