    • Scene Reconstruction from Multi-Scale Input Data 

      Fuhrmann, Simon (TU Darmstadt ULB, 2015-06-18)
      Geometry acquisition of real-world objects by means of 3D scanning or stereo reconstruction constitutes a very important and challenging problem in computer vision. 3D scanners and stereo algorithms usually provide geometry ...
    • Scheduling activities under spatial and temporal constraints to populate virtual urban environments 

      Jorgensen, Carl-Johan (Université Rennes 1, 2015-07-17)
      Crowd simulation models usually aim at producing visually credible crowds with the intent of giving life to virtual environments. Our work focusses on generating statistically consistent behaviours that can be used to pilot ...
    • Schnelle Kurven- und Flächendarstellung auf grafischen Sichtgeräten 

      Straßer, Wolfgang (1974-09-05)
      Für die Anwendung beim interaktiven Entwurf von Kurven und Flächen auf grafischen Sichtgeräten werden im ersten Teil der Arbeit bekannte mathematische Verfahren in einer kompakten, einheitlichen Matrizenschreibweise ...
    • The Secret of Appeal - Understanding Perception of Realistic and Stylized Faces 

      Zell, Eduard (Verlag Dr. Hut, 2018-07-16)
      Stylized characters are highly used in movies and games. Furthermore, stylization is mostly preferred over realism for the design of toys and social robots. However, the design process remains highly subjective because the ...
    • Selected Quality Metrics for Digital Passport Photographs 

      Gonzalez Castillo, Oriana Yuridia (Gonzalez Castillo, 12.12.2007)
      Passbilder spielen eine wichtige Rolle bei der Identifizierung von Personen. Da die Personenerkennunggegenwärtig immer mehr an Bedeutung gewinnt und die Genauigkeit derErkennung einen großen Einfluß auf verschiedene ...
    • SELF-DELAUNAY MESHES FOR SURFACES 

      Dyer, Ramsay (Dyer, 2010)
      In the Euclidean plane, a Delaunay triangulation can be characterized by the requirementthat the circumcircle of each triangle be empty of vertices of all other triangles. For triangulatinga surface S in R3, the Delaunay ...

    • Shape Deformations Based on Vector Fields 

      Freiherr von Funck, Wolfram Alexander (Freiherr von Funck, Wolfram Alexander, 2008-12-22)
      This thesis explores applications of vector field processing to shape deformations. We present a novel method to construct divergence-free vector fields which are used to deform shapes by vector field integration. ...
    • Shape Spaces from Morphing 

      Marc Alexa (Alexa, 2002)
      In dieser Arbeit werden Methoden zur Repr¨asentation der Gestalt oder Form von Objekten vorgestellt. Die Grundidee ist, die Form eines Objektes als Mischung anderer vorgegebener Formen zu beschreiben. Dazu wird das ...
