Generating Smooth High-Quality Isosurfaces for Interactive Modeling and Visualization of Complex Terrains
(The Eurographics Association, 2012)
In modeling and rendering of complex procedural terrains the extraction of isosurfaces is an important part. In this paper we introduce an approach to generate high-quality isosurfaces from regular grids at interactive ...
Registration of Temporal Ultrasonic Image Sequences Using Markov Random Fields
(The Eurographics Association, 2012)
Ultrasound perfusion imaging is a rapid and inexpensive technique which enables observation of a dynamic process with high temporal resolution. The image acquisition is disturbed by various motion influences due to the ...
Optimized Canonical Coordinate Frames for 3D Object Normalization
(The Eurographics Association, 2012)
In this paper, we describe a method to optimize an orthogonal system of axes for 3D objects in order to perform normalization with respect to orientation and scale. An energy function evaluates the quality of a system by ...
The Great Wall of Space-Time
(The Eurographics Association, 2012)
Understanding how data evolves in space and time is an essential task in many application domains. Despite the numerous visual methods that have been proposed to facilitate this task (e.g., showing the data on a map or ...
Screen Space Spherical Harmonic Occlusion
(The Eurographics Association, 2012)
In this paper we present a new algorithm for real-time directional occlusion sampling. We combine the real-time capabilities of Screen Space Ambient Occlusion (SSAO) with the Spherical Harmonics (SH) representation of local ...
Juggling Increases Interhemispheric Brain Connectivity: A Visual and Quantitative dMRI Study
(The Eurographics Association, 2012)
We use visualization to help analyze a diffusion magnetic resonance imaging study that has investigated the effects of learning how to juggle on nerve fiber microstructure in the human brain. Building on a standard voxel-wise ...
Visualizing Dynamic Call Graphs
(The Eurographics Association, 2012)
Visualizing time-varying call graphs is challenging due to vast amounts of data at many dimensions to be displayed: Hierarchically organized vertices with attributes, directed or undirected edges with weights, and time. ...
Segmentation of Vertebral Bodies in MR Images
(The Eurographics Association, 2012)
Segmentation of vertebral bodies is useful for diagnosis of certain spine pathologies, such as scoliosis, spondylolisthesis and vertebral fractures. In this paper, we present a fast and semi-automatic approach for spine ...
Hybrid Sample-based Surface Rendering
(The Eurographics Association, 2012)
The performance of rasterization-based rendering on current GPUs strongly depends on the abilities to avoid overdraw and to prevent rendering triangles smaller than the pixel size. Otherwise, the rates at which highresolution ...
Analysis of Vortex Merge Graphs
(The Eurographics Association, 2012)
We propose an analysis framework to investigate different flow quantities such as vorticity, λ<sub>2</sub> or the acceleration magnitude along vortex merge graphs and within their regions of influence. The ...
