  • Intrinsic image decomposition from multiple photographs 

    Laffont, Pierre-Yves (Laffont Pierre-Yves, 2012-10-12)
    Editing materials and lighting is a common image manipulation task that requires significantexpertise to achieve plausible results. Each pixel aggregates the effect of both materialand lighting, therefore standard color ...
  • Automated methods for audio-based music analysis with applications to musicology 

    Konz, Verena (Konz, 2012-11-09)
    This thesis contributes to bridging the gap between music information retrieval (MIR) and musicology. We present several automated methods for music analysis, which are motivated by concrete application scenarios being of ...
  • 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 ...
  • Topological analysis of discrete scalar data 

    Günther, David (Günther, 2012-12-18)
    This thesis presents a novel computational framework that allows for a robust extraction and quantification of the Morse-Smale complex of a scalar field given on a 2- or 3- dimensional manifold. The proposed framework is ...
