      The aim of this thesis was to eliminate essential deficits in the use of previous 3D GIS in an openly distributed GIS infrastructure. The increasing availability of three-dimensional city models poses a special problem, ...
    • Guided Interactive Volume Editing in Medicine 

      Karimov, Alexey (2016-06-28)
      Various medical imaging techniques, such as Computed Tomography, Magnetic Resonance Imaging, Ultrasonic Imaging, are now gold standards in the diagnosis of different diseases. The diagnostic process can be greatly improved ...
    • Guided qualitative and quantitative analysis of cardiac 4D PC-MRI blood flow data 

      Köhler, Benjamin (2016)
      The genesis and progression of cardiovascular diseases (CVDs) depend on various factors. A better comprehension of patient-specific blood flow hemodynamics has great potential to increase their diagnosis, support treatment ...
    • A Head Model with Anatomical Structure for Facial Modeling and Animation 

      Kähler, Kolja (2003)
      In this dissertation, I describe a virtual head model with anatomical structure. The model is animated in a physics-based manner by use of muscle contractions that in turn cause skin deformations; the simulation is ef ...
    • The high dynamic range imaging pipeline: Tone-mapping, distribution, and single-exposure reconstruction 

      Eilertsen, Gabriel (Linköping University Electronic Press, 2018-06-08)
      Techniques for high dynamic range (HDR) imaging make it possible to capture and store an increased range of luminances and colors as compared to what can be achieved with a conventional camera. This high amount of image ...
