  1. 1. A self-calibrating system for finger tracking using sound waves

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Linus Hammarlund; [2017]
    Nyckelord :cfrc; gcc-phat; srp-phat; self-calibration; toda; toa; Technology and Engineering; Mathematics and Statistics;

    Sammanfattning : In this thesis a system for tracking the fingers of a user using sound waves is developed. The proposed solution is to attach a small speaker to each finger and then have a number of microphones placed ad hoc around a computer monitor listening to the speakers. LÄS MER

  2. 2. Robust Time Difference Estimation for Unknown Microphone Positions with Reverberation

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Simon Segerblom Rex; [2015]
    Nyckelord :TDOA; RANSAC; GCC-PHAT; GCC; time difference; range difference; sound tracking; Technology and Engineering; Mathematics and Statistics;

    Sammanfattning : In this thesis a system is developed for robust time difference estimation for multiple microphones in reverberant environments, without any knowledge of the 3D positions of the microphones or the room. RANSAC is used to find line segments in sets of frames containing a number of the largest GCC-PHAT peaks. LÄS MER

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

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Damodar Reddy Naturi; [2012]
    Nyckelord :SRP-Phat; acoustics; camera tracking; GCC Phat;

    Sammanfattning : 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. LÄS MER
