  1. 1. 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.

  3. 2. 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

  4. 3. 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

  5. 4. Towards accessible content creation of real world objects for virtual environments

    Författare :Sverker Rasmuson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; voxels; compression; volumetric video; 3D reconstruction;

    Sammanfattning : 3D reconstruction is the general problem of creating 3D models from real world objects. In today's movie and games industry, there is an increasing demand for using real world content as assets in production. LÄS MER

  7. 5. Direct Fourier methods in 3D-reconstruction from cone-beam data

    Författare :Caroline Axelsson; Michel Defrise; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The problem of 3D-reconstruction is encountered in both medical and industrial applications of X-ray tomography. It would seem natural to recover volume data by just repeating 2D-reconstructions slice-by-slice. LÄS MER
