Audio person tracking in a smart-room environment
Alberto Abad, Carlos Segura, Duàn Macho, Javier Hernando, Climent Nadeu · 2006
Reliable measures of speaker positions are needed for computational perception of human activities taking place in a smartroom environment. In this work, it is described the development process and the experiments conducted in the design and implementation of an Audio Person Tracking system for smart-room environments. The proposed system is based on the SRP-PHAT algorithm, as it is known to perform robustly in most environmental conditions. Novelties proposed are aimed to enhance the accuracy of the system independently on the application scenario and to reduce the computational complexity.
