    • Continuity and Interpolation Techniques for Computer Graphics 

      González García, Francisco (González García, 2013)
      In Computer Graphics applications, it is a common practice to texture 3D models to applymaterial properties to them. Then, once the models are textured, they are deformedto create new poses that can be more appropriate for ...

    • Visual Analytics Approaches for Descriptor Space Comparison and the Exploration of Time Dependent Data 

      Bremm, Sebastian (Bremm, 2013-12-02)
      Modern technologies allow us to collect and store increasing amounts of data. However, their analysis is often difficult. For that reason, Visual Analytics combines data mining and visualization techniques to explore and ...

    • 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 ...

    • Non-Periodic Corner Tilingsin Computer Graphics 

      Schlömer, Thomas (Schlömer, 2012-11-16)
      Rendering computer-generated images is both memory and runtime intensive.This is particularly true in realtime computer graphics where large amounts ofcontent have to be produced very quickly and from limited data. ...

    • 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 ...
