We present a new image-based algorithm for surface reconstruction of moving garment from multiple calibrated video cameras. Using a color-coded cloth texture, we reliably match circular features between different camera views. As surface model we use an a priori known triangle mesh. By identifying the mesh vertices with texture elements we obtain a coherent(More)
Multi-touch hardware has only recently entered the mainstream of information technology. Interaction designers, product developers and users have been influenced by this development. In order to build multi-touch applications, programmers have created various reusable frameworks. To obtain an overview of this diversity, we present a list of criteria to(More)
We propose a method that extracts sparse and spatially localized deformation modes from an animated mesh sequence. To this end, we propose a new way to extend the theory of sparse matrix decompositions to 3D mesh sequence processing, and further contribute with an automatic way to ensure spatial locality of the decomposition in a new optimization framework.(More)

Bottom Row: the proposed compressed manifold modes (CMMs) have local support and are confined to specific local features like protrusions and ridges. Here, 8 of the CMMs(More)
The clinical behavior of meningiomas with a high proliferative potential was analyzed to determine if the bromodeoxyuridine (BUdR) labeling index (LI) could be used to predict recurrence and the time to reoperation. Each patient received an intraoperative infusion of BUdR to label cells in DNA synthesis; the percentage of S-phase cells, or BUdR LI, of each(More)
Wrinkles and folds play an important role in the appearance of real textiles. The way in which they form depends mainly on the bending properties of the specific material type. Existing approaches fail to reliably reproduce characteristic behaviour like folding and buckling for different material types or resolutions. It is therefore crucial for the(More)
Realistically eroded terrain is a base of almost every outdoor visualization for simulators or computer games. In order to achieve convincing results physically based erosion algorithms are necessary. We present a new method that combines a non-expensive fluid simulation with an erosion algorithm. Both parts are running at interactive rates so the artist is(More)
We present an algorithm for estimating dense image correspondences. Our versatile approach lends itself to various tasks typical for video post-processing, including image morphing, optical flow estimation, stereo rectification, disparity/depth reconstruction and baseline adjustment. We incorporate recent advances in feature matching, energy minimization,(More)
We present a comprehensive data-driven statistical model for skin and muscle deformation of the human shoulder-arm complex. Skin deformations arise from complex bio-physical effects such as non-linear elasticity of muscles, fat, and connective tissue; and vary with physiological constitution of the subjects and external forces applied during motion. Thus,(More)
The correct simulation and visualisation of textiles comprises many research fields such as mathematics, physics, materials science, and computer graphics. It consists of modelling the physical behaviour of textiles based on real data of garment patterns which have to be placed around an avatar. Therefore efficient numerical algorithms have to be developed(More)
