1. 21. Intelligent Camera Tracking using SRP-based sound Source localization in frequency domain

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Damodar Reddy Naturi; [2012]
   Keywords : SRP-Phat; acoustics; camera tracking; GCC Phat;

   Abstract : The Steered Response Power Phase Transform (SRP-PHAT) is one of the most robust methods among sound source localization operating in noisy and reverberant environments. Direction of Arrival (DOA) Estimation has important applications in human computer interfaces such as video conferencing, speech enhancement and speech recognition. READ MORE

3. 22. Microphone Array Wiener Beamforming with emphasis on Reverberation

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Vamsynagh Pedamallu; [2012]
