  1. 1. eHealth literacy and internet use for health information : a study in Swedish primary healthcare

    Författare :Anna Sjöström; Ulf Isaksson; Åsa Hörnsten; Senada Hajdarevic; Unn-Britt Johansson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eHealth; eHealth literacy; health literacy; nursing; primary healthcare; person-centred card care;

    Sammanfattning : Background: Primary healthcare (PHC) is facing significant challenges in Sweden and around the world. One way to address such challenges is through health-related Internet information (HRII) and other eHealth services, which are resources for high-quality, accessible and cost-effective care. LÄS MER

  3. 2. Multi-Camera Light Field Capture : Synchronization, Calibration, Depth Uncertainty, and System Design

    Författare :Elijs Dima; Mårten Sjöström; Roger Olsson; Ulf Assarsson; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Light field; Camera systems; Multiview; Synchronization; Camera calibration;

    Sammanfattning : The digital camera is the technological counterpart to the human eye, enabling the observation and recording of events in the natural world. Since modern life increasingly depends on digital systems, cameras and especially multiple-camera systems are being widely used in applications that affect our society, ranging from multimedia production and surveillance to self-driving robot localization.

  4. 3. On mapping of digital filter algorithms to hardware

    Författare :Oscar Gustafsson; Ulf Sjöström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we discuss various issues involving the design path for low power design of frequency-selective digital filters. As recursive filters have a bound on the minimal iteration period, Tmin we focus on these. Implementations that obtain Tmin are known as maximally fast. LÄS MER

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

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

    Sammanfattning : 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.
