Manual Clustering Refinement using Interaction with Blobs
(The Eurographics Association, 2007)
The huge amount of different automatic clustering methods emphasizes one thing: there is no optimal clustering method for all possible cases. In certain application domains, like genomics and natural language processing, ...
Dimensional Congruence for Interactive Visual Data Mining and Knowledge Discovery
(The Eurographics Association, 2007)
Many authors in the field of 3D human computer interaction have described the advantages of 3D user interfaces: Intuitive metaphors from daily life, immersive workspaces, virtual environments that closely resemble natural ...
A Tri-Space Visualization Interface for Analyzing Time-Varying Multivariate Volume Data
(The Eurographics Association, 2007)
The dataset generated by a large-scale numerical simulation may include thousands of timesteps and hundreds of variables describing different aspects of the modeled physical phenomena. In order to analyze and understand ...
See What You Know: Analyzing Data Distribution to Improve Density Map Visualization
(The Eurographics Association, 2007)
Density maps allow for visually rendering density differences, usually mapping density values to a grey or color scale. The paper analyzes the drawbacks arising from the commonly used strategies and introduces a novel ...
Animation of Orthogonal Texture-Based Vector Field Visualization
(The Eurographics Association, 2007)
This paper introduces orthogonal vector field visualization on 2D manifolds: a representation by lines that are perpendicular to the input vector field. Line patterns are generated by line integral convolution (LIC). This ...
Sonar Explorer: A New Tool for Visualization of Fish Schools from 3D Sonar Data
(The Eurographics Association, 2007)
We present a novel framework for analysis and visualization of fish schools in 3D sonar surveys. The 3D sonar technology is new and there have not been applications to visualize the data in 3D. We have created an application ...
Viewpoint Selection for Intervention Planning
(The Eurographics Association, 2007)
Viewpoint selection is crucial for medical intervention planning. The interactive exploration of a scene with 3d objects involves the systematic analysis of several anatomic structures. Viewpoint selection techniques enhance ...
Visualization Methods for Vortex Rings and Vortex Breakdown Bubbles
(The Eurographics Association, 2007)
Vortex breakdown bubbles are a subject which is of interest in many disciplines such as aeronautics, mixing, and combustion. Existing visualization methods are based on stream surfaces, direct volume rendering, tensor field ...
Feature Emphasis and Contextual Cutaways for Multimodal Medical Visualization
(The Eurographics Association, 2007)
Dense clinical data like 3D Computed Tomography (CT) scans can be visualized together with real-time imaging for a number of medical intervention applications. However, it is difficult to provide a fused visualization that ...
Functional Unit Maps for Data-Driven Visualization of High-Density EEG Coherence
(The Eurographics Association, 2007)
Synchronous electrical activity in different brain regions is generally assumed to imply functional relationships between these regions. A measure for this synchrony is electroencephalography (EEG) coherence, computed ...
