      Erdt, Marius (Erdt, 2012-06-13)
      In medical imaging, large amounts of data are created during each patient examination, especially using 3-dimensional image acquisition techniques such as Computed Tomography. This data becomes more and more difficult to ...

    • The Intrinsic Shape of Point Clouds 

      Ohrhallinger, Stefan (Ohrhallinger, 2012-07-12)
      Given a point cloud, in the form of unorganized points, the problem of automatically connecting the dots to obtain an aesthetically pleasing and piecewise-linear closed interpolating boundary shape has been extensively ...

    • Practical Real-Time Strategies for Photorealistic Skin Rendering and Antialiasing 

      Jimenez, Jorge (Jimenez, 2012-07-13)
      The first topic of this thesis, photorealistic skin rendering, is of extreme importance to create believable special effects in cinematography,but it has been ignored to an extent by the game industry. However, in the last ...

    • Algorithms for 3D Isometric Shape Correspondence - Algorithms for 3D Isometric Shape Correspondence 

      Sahillioglu, Yusuf (Sahillioglu, 2012-08-01)
      There are many pairs of objects in the digital world that need to be related before performing any comparison, transfer, or analysis in between. The shape correspondence algorithms essentially address this problem by taking ...

    • Real-Time Geometry Decompression on Graphics Hardware 

      Meyer, Quirin (Dr. Hut Verlag, 2012-08-01)
      Real-Time Computer Graphics focuses on generating images fast enough to cause the illusion of a continuous motion. It is used in science, engineering, computer games, image processing, and design. Special purpose graphics ...

    • Perceptual Display: Exceeding Display Limitations by Exploiting the Human Visual System 

      Didyk, Piotr (Didyk, Piotr, 2012-08-20)
      Existing displays have a number of limitations, which make it difficult to realistically reproduce real-world appearance; discrete pixels are used to represent images, which are refreshed only a limited number of times ...

    • Passive Spatio-Temporal Geometry Reconstruction of Human Faces at Very High Fidelity 

      Beeler, Thabo (Beeler, 2012-09-18)
      The creation of realistic synthetic human faces is one of the most important and at the same time also most challenging topics in computer graphics. The high complexity of the face as well as our familiarity with it renders ...

    • Perception-Augmenting Illumination 

      Solteszova, Veronika (Solteszova, 2012-10-04)
      At each stage of the visualization pipeline, the information is impeded by loss or by noise because of imprecise acquisition, storage limitations, and processing. Furthermore, it passes through the complex and not yet well ...
