  1. 1. Local visual feature based localisation and mapping by mobile robots

    Författare :Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile robotics; registration; localisation; SLAM; mapping; omnidirectional vision; 3D vision; appearance based; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : This thesis addresses the problems of registration, localisation and simultaneous localisation and mapping (SLAM), relying particularly on local visual features extracted from camera images. These fundamental problems in mobile robot navigation are tightly coupled. LÄS MER

  3. 2. Perceptually Motivated Constraints on 3D Visualizations

    Författare :Camilla Forsell; Mats Lind; Thomas Porathe; Uppsala universitet; []
    Nyckelord :Människa-dator-interaktion; Perception; 3D; Human-Computer Interaction; Information visualization; User studies; Människa-dator-interaktion;

    Sammanfattning : This thesis addresses some important characteristics of human visual perception and their implications for three-dimensional (3D) information visualization. The effort can be divided into two parts. First, findings from vision science are explored and validated. LÄS MER

  4. 3. The three-dimensional normal-distributions transform : an efficient representation for registration, surface analysis, and loop detection

    Författare :Martin Magnusson; Achim Lilienthal; Wolfram Burgard; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NDT; 3D sensing; surface representation; registration; loop detection; surface analysis; mobile robotics; localisation; mapping; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. LÄS MER

  5. 4. Visualizing Dynamics –The Perception of Spatiotemporal Data in 2D and 3D

    Författare :Andreas Kjellin; Mats Lind; Else Nygren; Kjell Ohlsson; Uppsala universitet; []
    Nyckelord :Människa-dator-interaktion; Human-Computer Interaction; Information Visualization; Usability; 2D; 3D; Cue Probability Learning; Space-time Cub; Människa-dator-interaktion;

    Sammanfattning : In many command and control situations the understanding of dynamic events is crucial. With today’s development of hard- and software architecture, we have the possibility to visualize data in two-dimensional (2D) and three-dimensional (3D) images. LÄS MER

  7. 5. Exploring the multiscale 3D architecture of human chromosome contact networks

    Författare :Dolores Bernenko; Ludvig Lizana; Martin Rosvall; Petter Holme; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; community detection; DNA 3D organization; Hi-C; network science; DNA-DNA contact data;

    Sammanfattning : Cells regulate genes to coordinate essential functions allowing cells to grow, divide, specialize, and respond to stresses. While regulatory proteins are the most common way to control these genes, the DNA’s 3D structure also plays a critical role as it affects how proteins access genes and how regulatory DNA elements interact over large genomic distances.
