  1. 1. Distance Functions and Image Processing on Point-Lattices : with focus on the 3D face- and body-centered cubic grids

    Författare :Robin Strand; Gunilla Borgefors; Stina Svensson; Christer Kiselman; David Coeurjolly; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Computerized image analysis; digital geometry; distance functions; non-standard grids; point-lattices; Image analysis; Bildanalys;

    Sammanfattning : There are many imaging techniques that generate three-dimensional volume images today. With higher precision in the image acquisition equipment, storing and processing these images require increasing amount of data processing capacity. Traditionally, three-dimensional images are represented by cubic (or cuboid) picture elements on a cubic grid. LÄS MER

  2. 2. Particle emissions from residential wood and biodiesel combustion

    Författare :Robin Nyström; Christoffer Boman; Dan Boström; Markus Broström; Michael Strand; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Combustion; biomass; wood; biodiesel; particulate matter; emissions; aerosols; physicochemical properties; size distribution; PAH;

    Sammanfattning : Emissions from anthropogenic combustion sources, such as vehicles and biomass combustion, contribute significantly to ambient particulate matter (PM) both on a local and global scale. Exposure to ambient PM and air pollution in general is linked to a variety of different health effects and it has been estimated that as many as 2. LÄS MER

  3. 3. Precise Image-Based Measurements through Irregular Sampling

    Författare :Teo Asplund; Robin Strand; Cris L. Luengo Hendriks; Matthew J. Thurley; Gunilla Borgefors; Hugues Talbot; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; image analysis; image processing; mathematical morphology; irregular sampling; adaptive morphology; missing samples; continuous morphology; path opening.; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Mathematical morphology is a theory that is applicable broadly in signal processing, but in this thesis we focus mainly on image data. Fundamental concepts of morphology include the structuring element and the four operators: dilation, erosion, closing, and opening. LÄS MER

  4. 4. Efficient GPU-based Image Registration : for Detailed Large-Scale Whole-body Analysis
