Kinematic ICP for Articulated Template Fitting
(The Eurographics Association, 2012)In this paper, we present an efficient optimization method to adapt an articulated 3D template model to a full or partial 3D mesh. The well-known ICP algorithm is enhanced to fit a generic template to a target mesh. Each ... -
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. ... -
3D Shape Matching based on Geodesic Distance Distributions
(The Eurographics Association, 2012)In this work, we present a signature for 3D shapes which is based on the distribution of geodesic distances. Our shape descriptor is invariant with respect to rotation and scaling as well as articulations of the object. ... -
Visualization and Exploration of Shape Variance for the Analysis of Cohort Study Data
(The Eurographics Association, 2012)In epidemiological studies, a group of people with common characteristics or experiences (a cohort) is studied including an analysis of socio-demographic as well as biological factors and correlations indicating per subject ... -
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 ... -
Markov Chain Driven Multi-Dimensional Visual Pattern Analysis with Parallel Coordinates
(The Eurographics Association, 2012)Parallel coordinates is a widely used visualization technique for presenting, analyzing and exploring multidimensional data. However, like many other visualizations, it can suffer from an overplotting problem when rendering ... -
Visualization of Scene Structure Uncertainty in a Multi-View Reconstruction Pipeline
(The Eurographics Association, 2012)This paper presents a novel, interactive visualization tool that allows for the analysis of scene structure uncer- tainty and its sensitivity to parameters in different multi-view scene reconstruction stages. Given a set ... -
Resolving Twisted Surfaces within an Iterative Refinement Surface Reconstruction Approach
(The Eurographics Association, 2012)We present a method which resolves twisted surface regions within a surface reconstruction approach that uses local refinement operations to iteratively fit a surface into an unorganized point cloud. We show that this local ... -
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 ... -
A Mixed Shape Space for Fast Interpolation of Articulated Shapes
(The Eurographics Association, 2012)Interpolation between compatible triangle meshes that represent different poses of some object is a fundamental operation in geometry processing. A common approach is to consider the static input shapes as points in a ... -
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 ... -
Cyclic Numerical Time Integration in Variational Non-Rigid Image Registration based on Quadratic Regularisation
(The Eurographics Association, 2012)In the present work, a novel computational framework for variational non-rigid image registration is discussed. The fundamental aim is to provide an alternative to approximate approaches based on successive convolution, ... -
Implicit Integral Surfaces
(The Eurographics Association, 2012)We present an implicit method for globally computing all four classic types of integral surfaces - stream, path, streak, and time surfaces - in 3D time-dependent vector fields. Our novel formulation is based on the ... -
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 ... -
Adaptive Treelet Meshes for Efficient Streak-Surface Visualization on the GPU
(The Eurographics Association, 2012)We describe a novel adaptive mesh representation for streak-surfaces. The surface is represented as a mesh of small trees of initial depth zero (treelets). This mesh representation allows for efficient integration, refinement, ... -
Illumination-Driven Opacity Modulation for Expressive Volume Rendering
(The Eurographics Association, 2012)Using classical volume visualization, typically a couple of isosurface layers are rendered semi-transparently to show the internal structures contained in the data. However, the opacity transfer function is often difficult ... -
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 ... -
Visualizing Solar Dynamics Data
(The Eurographics Association, 2012)Solar dynamics data, particularly those from the Solar Dynamics Observatory, are now available in a sheer volume that is hard to investigate with traditional visualization tools, which mainly display 2D images. While the ... -
Spectral Analysis of Higher-Order and BFECC Texture Advection
(The Eurographics Association, 2012)We present a spectral analysis of higher-order texture advection in combination with Back and Forth Error Compensation and Correction (BFECC). Semi-Lagrangian texture advection techniques exhibit high numerical diffusion, ...
