Microphone Array Based Surveillance System
Abstract
This work attempts to explore an alternative surveillance method through the usage of a microphone array. Most of the current audio based surveillance work focuses on the detection of a single sound source. For any future real world applications it is very plausible that multiple sound sources will occur simultaneously at some point in time. In this work a method of detecting and localizing multiple sound sources is presented. Three state-of-the-art techniques are given that put together allow the system to estimate the approximate location of one or multiple sound sources, separate the sounds, and then properly identify the sounds.
