Interactive, Graph-based Visual Analysis of High-dimensional, Multi-parameter Fluorescence Microscopy Data in Toponomics
Found in: IEEE Transactions on Visualization and Computer Graphics
By Steffen Oeltze,Wolfgang Freiler,Reyk Hillert,Helmut Doleisch,Bernhard Preim,Walter Schubert
Issue Date:December 2011
pp. 1882-1891
In Toponomics, the function protein pattern in cells or tissue (the toponome) is imaged and analyzed for applications in toxicology, new drug development and patient-drug-interaction. The most advanced imaging technique is robot-driven multi-parameter fluo...
Interactive Volume Visualization of General Polyhedral Grids
Found in: IEEE Transactions on Visualization and Computer Graphics
By Philipp Muigg,Markus Hadwiger,Helmut Doleisch,Eduard Gröller
Issue Date:December 2011
pp. 2115-2124
This paper presents a novel framework for visualizing volumetric data specified on complex polyhedral grids, without the need to perform any kind of a priori tetrahedralization. These grids are composed of polyhedra that often are non-convex and have an ar...
Visual Exploration of Nasal Airflow
Found in: IEEE Transactions on Visualization and Computer Graphics
By Stefan Zachow, Philipp Muigg, Thomas Hildebrandt, Helmut Doleisch, Hans-Christian Hege
Issue Date:November 2009
pp. 1407-1414
Rhinologists are often faced with the challenge of assessing nasal breathing from a functional point of view to derive effective therapeutic interventions. While the complex nasal anatomy can be revealed by visual inspection and medical imaging, only vague...
Hypothesis Generation in Climate Research with Interactive Visual Data Exploration
Found in: IEEE Transactions on Visualization and Computer Graphics
By Johannes Kehrer, Florian Ladstädter, Philipp Muigg, Helmut Doleisch, Andrea Steiner, Helwig Hauser
Issue Date:November 2008
pp. 1579-1586
One of the most prominent topics in climate research is the investigation, detection, and allocation of climate change. In this paper, we aim at identifying regions in the atmosphere (e.g., certain height layers) which can act as sensitive and robust indic...
Interactive Visual Analysis of Perfusion Data
Found in: IEEE Transactions on Visualization and Computer Graphics
By Steffen Oeltze, Helmut Doleisch, Helwig Hauser, Philipp Muigg, Bernhard Preim
Issue Date:November 2007
pp. 1392-1399
Perfusion data are dynamic medical image data which characterize the regional blood flow in human tissue. These data bear a great potential in medical diagnosis, since diseases can be better distinguished and detected at an earlier stage compared to static...
Interactive Visual Exploration and Analysis of Multivariate Simulation Data
Found in: Computing in Science and Engineering
By Helmut Doleisch,Helwig Hauser
Issue Date:March 2012
pp. 70-77
The interactive visual exploration of large and complex simulation datasets has become an important methodology that improves data analysis for scientists and professional practitioners.
Interactive Visual Analysis of Heterogeneous Scientific Data across an Interface
Found in: IEEE Transactions on Visualization and Computer Graphics
By Johannes Kehrer, Philipp Muigg, Helmut Doleisch, Helwig Hauser
Issue Date:July 2011
pp. 934-946
We present a systematic approach to the interactive visual analysis of heterogeneous scientific data. The data consist of two interrelated parts given on spatial grids over time (e.g., atmosphere and ocean part from a coupled climate model). By integrating...
Visualizing Statistical Properties of Smoothly Brushed Data Subsets
Found in: Information Visualisation, International Conference on
By Andrea Unger, Phillip Muigg, Helmut Doleisch, Heidrun Schumann
Issue Date:July 2008
pp. 233-239
In many application fields, the statistical properties of data sets are of great interest for data analysts. Since local variations can occur especially in large datasets, it is useful to visualize not only global values, but also the properties of user-de...
Interactive cross-detector analysis of vortical flow data
Found in: Coordinated and Multiple Views in Exploratory Visualization, International Conference on
By Raphael Burger, Philipp Muigg, Helmut Doleisch, Helwig Hauser
Issue Date:July 2007
pp. 98-110
In this paper we discuss the application of multiple linked views for advanced vortex investigation in flow data. Local feature detectors and additional measures integrate into an interactive flow feature detection system based on multiple linked views. We...
Visual Analysis and Exploration of Fluid Flow in a Cooling Jacket
Found in: Visualization Conference, IEEE
By Robert S. Laramee, Christoph Garth, Helmut Doleisch, Jurgen Schneider, Helwig Hauser, Hans Hagen
Issue Date:October 2005
pp. 79
We present a visual analysis and exploration of fluid flow through a cooling jacket. Engineers invest a large amount of time and serious effort to optimize the flow through this engine component because of its important role in transferring heat away from ...
Angular Brushing of Extended Parallel Coordinates
Found in: Information Visualization, IEEE Symposium on
By Helwig Hauser, Florian Ledermann, Helmut Doleisch
Issue Date:October 2002
pp. 127
In this paper we present angular brushing for parallel coordinates (PC) as a new approach to highlighting rational data-properties, i.e., features which — in a non-separable way — depend on two data dimensions. We also demonstrate smooth brushing as an int...
