  1. 1. Computer-Aided Characterization of Lung - Segmentation and Vessel Tree Analysis Algorithms for Clinical Research Applications

    University essay from KTH/Fysik

    Author : Daniel Karoumi; [2023]
    Keywords : Lung; lung segmentation; NSIP; IPF; lung vessels; lung morphometry; 3D Slicer; Lunga; lungsegmentering; NSIP; IPF; lungkärl; lung morfometri; 3D Slicer;

    Abstract : The initial stage of a lung examination involves the segmentation of a CT image, a process that has been put under a lot of pressure with the high demand for chest scans and accurate segmentations. Current automatic segmentation algorithms are either non-robust for different datasets, not easily accessible, or time-consuming. READ MORE

  2. 2. Creating virtual forests from public map data

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Axel Kappel; William Engman; [2022]
    Keywords : Forest Visualization; Map data; 3D; Unity; Mapbox;

    Abstract : Modern tools in the forest management industry lack the features to properly visualizeforests. This study explores the possibilities of recreating real-world forests in a three-dimensional virtual environment to give users the opportunity to remotely view whattheir forest looks like. To keep accessibility high, public map data was used. READ MORE

  3. 3. Alpha Tested Geometry in DXR : Performance Analysis of Asset Data Variations

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Tobias Fast; [2020]
    Keywords : ray tracing; alpha testing; texture format; rendering; tessellation; strålspårning; alfa testning; rendering; textur format; tesselering;

    Abstract : Background. Ray tracing can be used to achieve hyper-realistic 3D rendering but it is a computationally heavy task. Since hardware support for real-time ray tracing was released, the game industry has been introducing this feature into games. READ MORE

  4. 4. Reconstruction of trees from 3D point clouds

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Martin Stålberg; [2017]
    Keywords : Bayes; Bayesian inference; point cloud; pointcloud; 3D; tree; trees; reconstruction; Matlab; Povray; Arbaro; model; LIDAR; Hough transform; cylinder; geometry; heuristic; Australia; Australian Centre for Field Robotics; spherical grid; icosahedron; likelihood; intersection; artificial data; color encoded; depth map; coordinate map; ray tracing;

    Abstract : The geometrical structure of a tree can consist of thousands, even millions, of branches, twigs and leaves in complex arrangements. The structure contains a lot of useful information and can be used for example to assess a tree's health or calculate parameters such as total wood volume or branch size distribution. READ MORE

  5. 5. Studies of pyridine in water clusters with synchrotron radiation and 3D momentum spectrometry

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Benjamin Bolling; [2017]
    Keywords : Physics and Astronomy;

    Abstract : By using the site-selectivity enabled by synchrotron radiation, we can choose the ionization site on a molecule. Core-ionization can result in that the molecule dissociates into charged (and uncharged) ions. With mass spectroscopy, the dissociated fragments’ mass-over-charge can be identified in a time-of-flight spectrum. READ MORE
