    Our paper “Extraction of Dominant Extremal Structures in Volumetric Data using Separatrix Persistence” has been accepted for the Computer Graphics Forum.   Extremal lines and surfaces are features of a 3D scalar field where the scalar function becomes minimal or maximal with respect to a local neighborhood. These features are important in many applications,...

    Paper accepted at NORDIA workshop at ECCV 2012

    by  • August 3, 2012

    Our paper “Correspondences of persistent feature points on near-isometric surfaces.” has been accepted at the 5th Workshop on Non-Rigid Shape Analysis and Deformable Image Alignment (NORDIA), which will take place at the ECCV 2012. In this paper, we present an algorithmic pipeline to find correspondences between persistent feature points on near-isometric surfaces based on...

    Paper on controlled extrema will be presented at SGP 2012

    by  • July 1, 2012

    Our paper Smooth Shape-Aware Functions with Controlled Extrema will be presented at SGP 2012 in Tallinn, Estonia. Functions that optimize Laplacian-based energies have become popular in geometry processing, e.g. for shape deformation, smoothing, multiscale kernel construction and interpolation. Minimizers of Dirichlet energies, or solutions of Laplace equations, are harmonic functions that enjoy the maximum...

    Characteristic Curves of Vector Fields

    by  • June 8, 2012

    Flows of fluids or gases are of great importance in many technical processes. For example, designing a fuel efficient car involves reducing its aerodynamic drag. To this end, the flow around the car is simulated with a computer program. A subsequent flow analysis reveals vortex structures, which usually have a negative influence on the...

    Feature-Based Data Analysis

    by  • April 11, 2012

    Computing power increases constantly. While the fastest supercomputer in 1993 had a performance of 59.7 GFlop/s, we are now clearly in the petascale era with twenty installations breaching the 1 PFlop/s barrier (see TOP500 Supercomputer Sites). Along with the computing power, the size and complexity of simulation results is increasing as well. In many...
