Efficient and Robust Annotation of Motion Capture Data
(ACM SIGGRAPH / Eurographics Association, 2009)
In view of increasing collections of available 3D motion capture (mocap) data, the task of automatically annotating large sets of unstructured motion data is gaining in importance. In this paper, we present an efficient ...
Pre-convolved Radiance Caching
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter-pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both ...
Extended Branch Decomposition Graphs: Structural Comparison of Scalar Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a method to find repeating topological structures in scalar data sets. More precisely, we compare all subtrees of two merge trees against each other - in an efficient manner exploiting redundancy. This provides ...
Microtiles: Extracting Building Blocks from Correspondences
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
In this paper, we develop a theoretical framework for characterizing shapes by building blocks. We address two questions: First, how do shape correspondences induce building blocks? For this, we introduce a new representation ...
Optimizing Disparity for Motion in Depth
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Beyond the careful design of stereo acquisition equipment and rendering algorithms, disparity post-processing has recently received much attention, where one of the key tasks is to compress the originally large disparity ...
Enhancement of Bright Video Features for HDR Displays
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
To utilize the full potential of new high dynamic range (HDR) displays, a system for the enhancement of bright luminous objects in video sequences is proposed. The system classifies clipped (saturated) regions as lights, ...
Combining Confocal Imaging and Descattering
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
In translucent objects, light paths are affected by multiple scattering, which is polluting any observation. Confocal imaging reduces the influence of such global illumination effects by carefully focusing illumination and ...
Spherical Barycentric Coordinates
(The Eurographics Association, 2006)
We develop spherical barycentric coordinates. Analogous to classical, planar barycentric coordinates that describe the positions of points in a plane with respect to the vertices of a given planar polygon, spherical ...
Robust Filtering of Noisy Scattered Point Data
(The Eurographics Association, 2005)
In this paper, we develop a method for robust filtering of a noisy set of points sampled from a smooth surface. The main idea of the method consists of using a kernel density estimation technique for point clustering. ...
Connectivity Transformation for Mesh Metamorphosis
(The Eurographics Association, 2004)
In previous mesh morphing techniques, the vertex set and connectivity of an in-between mesh are fixed and only the vertex positions are interpolated between input meshes. With this restriction, to accurately represent both ...
