    Författare :Johannes Karlsson; Mikael Skoglund; Markus Flierl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative communication; wireless sensor networks; low-delay transmission; joint source-channel coding; estimation; quantization; Telecommunication; Telekommunikation;

    Sammanfattning : With the increasing popularity and relevance of ad-hoc wireless sensor networks, cooperative transmission is more relevant than ever. In this thesis, we consider methods for optimization of cooperative transmission schemes in wireless sensor networks. LÄS MER

  3. 2. Feature-Based Image Processing for Rendering, Compression, and Visual Search

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

    Sammanfattning : 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. LÄS MER

  4. 3. Coding of three-dimensional video content : Depth image coding by diffusion

    Författare :Yun Li; Mårten Sjöström; Ulf Jennehag; Roger Olsson; Markus Flierl; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Three-dimensional (3D) movies in theaters have become a massive commercial success during recent years, and it is likely that, with the advancement of display technologies and the production of 3D contents, TV broadcasting in 3D will play an important role in home entertainments in the not too distant future. 3D video contents contain at least two views from different perspectives for the left and the right eye of viewers.

  5. 4. Orthonormal Motion-Adaptive Transforms for Image Sequences

    Författare :Du Liu; Markus Flierl; Peter Schelkens; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this thesis, we propose and discuss a class of motion-adaptive transforms (MAT) to describe the temporal correlation in image sequences for compression. The temporal correlation is based on motion models, and undirected graphs are used to represent this correlation in image sequences. The transforms are adaptive to general motion fields. LÄS MER

  7. 5. Compression-based Data Identification and Representation Learning

    Författare :Hanwei Wu; Markus Flierl; Mikael Skoglund; Conci Nicola; KTH; []
