Two-Colored Pixels
(The Eurographics Association and Blackwell Publishing Ltd, 2010)
In this paper we show how to use two-colored pixels as a generic tool for image processing. We apply two-colored pixels as a basic operator as well as a supporting data structure for several image processing applications. ...
A Practical Guide to Polygon Mesh Repairing
(The Eurographics Association, 2012)
Digital 3D models are key components in many industrial and scientific sectors. In numerous domains polygonmeshes have become a de facto standard for model representation. In practice meshes often have a number ofdefects ...
Freeform Shape Representations for Efficient Geometry Processing
(Eurographics Association, 2003)
The most important concepts for the handling and storage of freeform shapes in geometry processing applications are parametric representations and volumetric representations. Both have their specific advantages and drawbacks. ...
Ad-Hoc Multi-Displays for Mobile Interactive Applications
(The Eurographics Association, 2010)
We present a framework which enables the combination of different mobile devices into one multi-display such that visual content can be shown on a larger area consisting, e.g., of several mobile phones placed arbitrarily ...
Geometric Modeling Based on Polygonal Meshes
(The Eurographics Association, 2008)
Polygonal meshes are nowadays intensively used in many different areas of computer graphics and geometry processing. In classical CAGD polygonal meshes developed into a valuable alternative to traditional spline surfaces, ...
High-Performance Image Filters via Sparse Approximations
(ACM, 2020)
We present a numerical optimization method to find highly efficient (sparse) approximations for convolutional image filters. Using a modified parallel tempering approach,we solve a constrained optimization that maximizes ...
High-Resolution Volumetric Computation of Offset Surfaces with Feature Preservation
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a new algorithm for the efficient and reliable generation of offset surfaces for polygonal meshes. The algorithm is robust with respect to degenerate configurations and computes (self-)intersection free offsets ...
Fast and Robust QEF Minimization using Probabilistic Quadrics
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Error quadrics are a fundamental and powerful building block in many geometry processing algorithms. However, finding the minimizer of a given quadric is in many cases not robust and requires a singular value decomposition ...
Geodesic Distance Computation via Virtual Source Propagation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
We present a highly practical, efficient, and versatile approach for computing approximate geodesic distances. The method is designed to operate on triangle meshes and a set of point sources on the surface. We also show ...
Learning Direction Fields for Quad Mesh Generation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
State of the art quadrangulation methods are able to reliably and robustly convert triangle meshes into quad meshes. Most of these methods rely on a dense direction field that is used to align a parametrization from which ...
