  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. Microphone Array Wiener Beamforming with modeling of SRP- PHAT for Speaker Localization

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :SRISESHUKUMAR BASAVA; [2012]
    Nyckelord :MIcrophone array; Wiener beamforming; Source localization;

    Sammanfattning : The use of microphone arrays to acquire and recognize speech in meetings (conference) poses several problems for speech processing as there exist many speakers within a small space, typically around a table. The necessity to design a suitable microphone array system with minimum noise and more efficient localization algorithms is drawing attention of researchers to work on it. LÄS MER

  3. 3. Multi Channel Sub Band Wiener Beamformer

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Rajesh Amerineni; [2012]
    Nyckelord :Reverberation; Linear Microphone array; WOLA Filter Bank; Wiener Beamformer; SRP-PHAT;

    Sammanfattning : With the recent advance in microphone array speech processing, achieving robustness of speaker localization becomes most significant aspect. At the same time considerable research growth is performed in developing the multiple microphone sensors equipped rooms are developed also called as smart rooms for real time applications. LÄS MER

  4. 4. 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

  5. 5. Microphone Array Wiener Beamforming with emphasis on Reverberation

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Vamsynagh Pedamallu; [2012]
    Nyckelord :reverberation; wiener; beamforming; PESQ; SRP-PHAT;

    Sammanfattning : Effective speech communication using microphone array is getting significant research in speech acquisition methods such as speaker localization, noise reduction and tracking. To locate the accurate Direction of Arrival (DOA) from the source, it is necessary to design a suitable microphone array system with noise reduction capability as well as efficiency in speaker localization.
