  3. 12. Research and optimization of a H.264AVC motion estimation algorithm based on a 3G network

    University essay from Institutionen för informationsteknologi

    Author : Ou Yu; [2013]
    Keywords : ;

    Abstract : The new video codec standard H.264/AVC is jointly developed by ISO/IEC Moving Picture Expert Group MPEG and ITU-T Video Coding Experts Group [1] [2], VCEG. It has higher coding efficiency than the MPEG-4, thus could be applied to high definition application in low bit-rate wireless environment.[3] However H. READ MORE

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

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : SRISESHUKUMAR BASAVA; [2012]
    Keywords : MIcrophone array; Wiener beamforming; Source localization;

    Abstract : 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. READ MORE
