Information-based Transfer Functions for Multimodal Visualization [article]

Martin Haidacher, Stefan Bruckner, Armin Kanitsar, M. Eduard Gröller

Computation of More Channels in Protein Molecules [article]

Petr Beneš, Petr Medek, Jiri Sochor
2008 Eurographics Workshop on Visual Computing for Biomedicine  
In this paper we propose a new adaptive method for computation of more channels. This new method is piloted on a real data and results are compared with channels identified by chemists as relevant.  ...  Chemists also require that more than one ideal channel be computed in a static protein molecule.  ...  A method proposed in [YFW * 08, YH08] combines both these approaches by computing the Voronoi diagram not for atom centers but for points sampled on the surface of atoms.  ...

Visually Guided Mesh Smoothing for Medical Applications [article]

Tobias Moench, Christoph Kubisch, Kai Lawonn, Ruediger Westermann, Bernhard Preim
2012 Eurographics Workshop on Visual Computing for Biomedicine  
Depending on the number of vertices and the filter algorithm, computation time may vary strongly and interfere with an interactive mesh generation procedure.  ...  Based on a GPU mesh smoothing implementation, model quality is evaluated in real-time and provided to the user as quality graphs to support the mental optimization of input parameters.  ...  For these exemplary filters, computation takes roughly a few seconds for typical anatomical surface models (e.g., <500,000 vertices) on a current CPU using only one core.  ...
