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 ...
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 ...
Interactive Comparative Visualization of Multimodal Brain Tumor Segmentation Data
(The Eurographics Association, 2013)
We present a visualization system for the analysis of multi-modal segmentation data of brain tumors. Our system is designed to allow researchers and doctors a further investigation of segmented tumor data beyond a quantitative ...
Modeling Incremental Visualizations
(The Eurographics Association, 2013)
An increasing number of applications call for the incremental/iterative drawing of a visualization. That is an obvious requirement when dealing with continuously changing data, like the emerging field of data streams or ...
Simulation of Time-of-Flight Sensors using Global Illumination
(The Eurographics Association, 2013)
Time-of-Flight (ToF) cameras use specialized sensors and modulated infrared light to simultaneously obtain depth, amplitude and intensity images. Depth images from such cameras suffer from various errors which exhibit a ...
Non-Sampled Anti-Aliasing
(The Eurographics Association, 2013)
In this paper we present a parallel method for high-quality edge anti-aliasing in rasterization. In contrast to traditional graphics hardware methods, which rely on massive oversampling to combat aliasing issues, we evaluate ...
Visualizing Contour Distributions in 2D Ensemble Data
(The Eurographics Association, 2013)
Overlaid plots of iso-contours in individual members of a scalar ensemble field are a popular concept to visualize the data uncertainty. However, such plots do not allow inferring on the spatial cumulative probability ...
Determining and Visualizing Potential Sources of Floods
(The Eurographics Association, 2013)
In this paper, we visually analyze spatio-temporal patterns of different hydrologic parameters relevant for flooding. On the basis of data from climate simulations with a high resolution regional atmosphere model, several ...
Image Based Rendering from Perspective and Orthographic Images for Autostereoscopic Multi-View Displays
(The Eurographics Association, 2013)
Current autostereoscopic (AS) multi-view displays for video that are targeted at the market allow typically up to 60 frames per second and offer between 20 and 60 different views per pixel. Future full parallax AS displays ...
Transfusive Weights for Content-Aware Image Manipulation
(The Eurographics Association, 2013)
Many image editing operations, such as colorization, matting or deformation, can be performed by propagating user-defined sparse constraints (e.g. scribbles) to the rest of the image using content-aware weight functions. ...
