      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 ...

    • 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 ...

    • Quadrilateral Surface Mesh Generationfor Animation and Simulation 

      Bommes, David (Bommes, 2012-10-11)
      Accurately describing the geometry of objects in a digital environment, i.e. computers, isan essential ingredient in many of nowadays applications. Often it is desired to forecastthe behavior of real phenomena which depend ...

    • A Frequency Analysis of Light Transport: from Theory to Implementation 

      Belcour, Laurent (Belcour, 2012-10-30)
      The simulation of complex light effects such as depth-of-field, motionblur or scattering in participating media requires a tremendous amountof computation. But the resulting pictures are often blurry. We claimthat those ...

    • 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 ...

    • Privacy and Security Assessment of Biometric Template Protection 

      Zhou, Xuebing (Zhou, 2011-09-19)
      Biometrics enables convenient authentication based on a person s physical or behavioral characteristics. In comparisonwith knowledge- or token-based methods, it links an identity directly to its owner. Furthermore, it can ...

    • GPU Data Structures for Graphics and Vision 

      Ziegler, Gernot (Ziegler, 2011-05-06)
      Graphics hardware has in recent years become increasingly programmable, and its programming APIs use the stream processor model to expose massive parallelization to the programmer. Unfortunately, the inherent restrictions ...
