  2. 1. Coding of three-dimensional video content : Depth image coding by diffusion

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

    Abstract : 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.

  4. 2. Coding of Three-dimensional Video Content : Diffusion-based Coding of Depth Images and Displacement Intra-Coding of Plenoptic Contents

    Author : Yun Li; Mårten Sjöström; Ulf Jennehag; Roger Olsson; Touradj Ebrahimi; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In recent years, the three-dimensional (3D) movie industry has reaped massive commercial success in the theaters. With the advancement of display technologies, more experienced capturing and generation of 3D contents, TV broadcasting, movies, and games in 3D have entered home entertainment, and it is likely that 3D applications will play an important role in many aspects of people's life in a not distant future.

  5. 3. Cursed complexity. Computational properties of subcortical neuronal microcircuitry in sensorimotor control

    Author : Anton Spanne; Hjärnans sensorimotoriska funktioner; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spike firing statistics; spontaneous activity; sensorimotor control; tactile processing; cuneate nucleus; sparse coding; spinal border cells; cerebellum;

    Abstract : One of the big obstacles for understanding the nervous system is its inherent complexity. It poses problems when interpreting both experimental and theoretical studies since we are currently forced to consider only reduced variants of the actual circuitry of the brain. READ MORE

  6. 4. Coding and Transmission Strategies for Secrecy

    Author : Mattias Andersson; Mikael Skoglund; Matthieu Bloch; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis we consider several problems relating to information theoretic security. The wiretap channel is the simplest information theoretic setting which takes security into account, and in the first chapters of the thesis we design some practical coding schemes for this channel model.

  7. 5. Motion estimation for perceptual image sequence coding

    Author : Kenneth Andersson; Håkon Husøy; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Since the advent of television obtaining high perceived quality using a limited bandwidth has been an important issue. This thesis proposes new methods for exploitation of temporal and perceptual redundancy in image sequences to achieve lower coding rate and/or higher visual quality. READ MORE
