  1. 6. From experiments with images to 3D models

    Författare :Henrike Häbel; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal particle aggregation; Anisotropy; mass transport; image analysis; Gibbs point processes; porous polymer blended films; porous polymer blended films;

    Sammanfattning : For developing the next generation sustainable materials, it is often crucial to understand and control their properties and function. This work presents cross-disciplinary research starting with experimentally fabricated porous soft biomaterials and images of their micro-structure obtained by electron or laser microscopy. LÄS MER

  3. 7. Towards unbiased 3D reconstruction : in single-particle cryo-electron microscopy

    Författare :Dominika Elmlund; Hans Hebert; Sarah Butcher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioengineering; Bioteknik;

    Sammanfattning : Cryo-electron microscopy of freestanding molecules (single-particles) plays a pivotal role in the difficult and pressing challenge of determining the structures of large macromolecular complexes. Molecular volumes are generated by aligning large sets of randomly oriented two-dimensional (2D) projection images in three dimensions (3D) before reconstruction is performed using tomographic techniques.

  4. 8. Classification and Localization of Vehicle Occupants Using 3D Range Images

    Författare :Pandu Ranga Rao Devarakota; Bjorn Ottersten; Hamid Krim; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : This thesis deals with the problem of classifying automotive vehicle occupants and estimating their position. This information is critical in designing future smart airbag systems providing maximum protection for passengers. LÄS MER

  5. 9. Techniques for Fast and High-Quality 3D Reconstruction of General Scenes

    Författare :Sverker Rasmuson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; voxels; 3D reconstruction; computer vision; computer graphics; volumetric video;

    Sammanfattning : This thesis is a collection of techniques used for 3D reconstruction; the creation of 3D models from real world objects or scenes. Given the increase in accuracy, robustness and speed of modern methods and algorithms, new and exciting applications of this technology is constantly appearing. LÄS MER

  7. 10. Optimization Methods for 3D Reconstruction : Depth Sensors, Distance Functions and Low-Rank Models

    Författare :Erik Bylow; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; 3D Reconstruction;

    Sammanfattning : This thesis explores methods for estimating 3D models using depth sensors andfinding low-rank approximations of matrices. In the first part we focus on how toestimate the movement of a depth camera and creating a 3D model of the scene. LÄS MER
