  1. 1. Video Signal Processing: Compression Segmentation and Tracking

    University dissertation from Chalmers University of Technology

    Author : Andrew Backhouse; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informationsteknik; Information technology; Signalbehandling; Signal processing;

    Abstract : This thesis considers three separate research problems within the field of video processing.The first is concerned with segmenting an image, the second with tracking an object and the third with the communication of video across an unreliable network. Segmentation is an application-specific problem. READ MORE
