  2. 16. Methods for Objective and Subjective Video Quality Assessment and for Speech Enhancement

    Author : Muhammad Shahid; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Video Quality Assessment; No-Reference Methods; Reduced-Reference Methods; Subjective Experiments; Speech Enhancement; Adaptive Gain Equalizer;

    Abstract : The overwhelming trend of the usage of multimedia services has raised the consumers' awareness about quality. Both service providers and consumers are interested in the delivered level of perceptual quality. The perceptual quality of an original video signal can get degraded due to compression and due to its transmission over a lossy network. READ MORE

  4. 17. Interpolation Techniques with Applications in Video Coding

    Author : Jens Ogniewski; Per-Erik Forssén; Haibo Li; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Recent years have seen the advent of RGB+D video (color+depth video), which enables new applications like free-viewpoint video, 3D and virtual reality. This is however achieved by adding additional data, thus increasing the bitrate. READ MORE

  5. 18. Development, analysis and implementation of pre-processing video filters

    Author : Håkan Norell; Mattias O´Nils; Danny Crookes; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : The usage of video systems in households and industry has increased rapidly over the past few years. The benefits of visual processing, control and inspection have offered great opportunities for real-time video processing systems (RTVPS) for the general public as well as for heavy industries.

  6. 19. Sparse representation of visual data for compression and compressed sensing

    Author : Ehsan Miandji; Jonas Unger; Anders Ynnerman; Hendrik P. A. Lensch; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The ongoing advances in computational photography have introduced a range of new imaging techniques for capturing multidimensional visual data such as light fields, BRDFs, BTFs, and more. A key challenge inherent to such imaging techniques is the large amount of high dimensional visual data that is produced, often requiring GBs, or even TBs, of storage. READ MORE

  7. 20. Feature-Based Image Processing for Rendering, Compression, and Visual Search

    Author : Haopeng Li; Markus Flierl; Peter Eisert; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Visual communication, vivid, meaningful, and creative, permits a way to express information visually. The communication media, by images, graphs and videos, passes informative color and shape to human perception sensors. READ MORE
