Neighbor Embedding by Soft Kendall Correlation
(The Eurographics Association, 2013)
Correlation-based embedding of complex data relationships in a Euclidean space is studied. The proposed soft formulation of Kendall correlation allows for gradient-based optimization of scatter point neighborhood relationships ...
Total Euler Characteristic as a Noise Measure to aid Transfer Function Design
(The Eurographics Association, 2013)
For image-based, semi- or fully automated design of transfer functions for direct volume rendering, it is beneficial to have an estimation of the noise level in the rendered image. A topology-motivated noise measure is ...
Illustrative Rendering of Vortex Cores
(The Eurographics Association, 2013)
Vortices are features crucial for understanding transitional and turbulent flow fields, and have often been visualized using isosurfaces, hulls, and line-like structures. However, they have not been represented in a ...
Multilevel Cloth Simulation using GPU Surface Sampling
(The Eurographics Association, 2013)
Today most cloth simulation systems use triangular mesh models. However, regular grids allow many optimizations as connectivity is implicit, warp and weft directions of the cloth are aligned to grid edges and distances ...
Mobile Image Retargeting
(The Eurographics Association, 2013)
We propose an algorithm for axis-aligned content-aware image retargeting that is specifically optimized for mobile devices, and we show that interactive image retargeting is possible even with a low-power, mobile CPU. Our ...
MLMD: Multi-Layered Visualization for Multi-Dimensional Data
(The Eurographics Association, 2013)
In this paper, we propose and implement a multi-layered visualization technique in 3D space called Multi-Layered Visualization for Multi-Dimensional Data (MLMD) with its corresponding interaction techniques, for visualizing ...
Parallelized Global Brain Tractography
(The Eurographics Association, 2013)
Most brain tractography algorithms suffer from lower accuracy, because they use only information in a certain neighborhood and reconstruct the tracts independently. Global brain tractography algorithms compensate the lack ...
Modeling Large Scale Clouds from Satellite Images
(The Eurographics Association, 2013)
Visualization of satellite cloud images plays an important role in atmosphere analysis and weather prediction. However, reconstruction of meaningful 3D clouds is a challenging problem due to the 2D nature of the input data. ...
Towards a Structured Analysis of Quantitative Descriptors from Segmented Biological Image Data
(The Eurographics Association, 2013)
Topological and morphological descriptions of (sub-)cellular structures play a central role in the understanding of biological processes. Deriving such descriptions from image data, however, is a challenging task that has ...
Bezier Crust on Quad Subdivision Surface
(The Eurographics Association, 2013)
Subdivision surfaces have been widely used in computer graphics and can be classified into two categories, approximating and interpolatory. Representative approximating schemes are Catmull-Clark (quad) and Loop (triangular). ...
