The central metaphor to access information is a virtual postcard with one front and a customizable number of back sides that provide details about exhibits to museum visitors in textual and image form. Back sides can link to others cards. Access to these postcards is possible through one or more navigation views that can be navigated to from a navigation bar. The entry point to the application is designed as a multitouch interactive pile of cards in a playful manner that allows visitors of any age an easy approach to the presentation and interaction metaphor. To directly access a certain postcard, a mosaic view can be uitilized to provide an overview about all available exhibits. A category view groups postcards into themes. Locating artefacts on a zoomable map or exhibition floor plan allows for conveying information about spatial contexts between different objects and their location. Furthermore, contexts can be illustrated with a two stage view comprising an overview and corresponding detail views to provide further insights into the spatial, temporal, and thematic contexts of artefacts. The application scaffolding allows the design of bilingual presentations to support exhibitions with an international audience. The logo of the presenting institution or exhibition can be incorporated to display the the kiosk's corporate design branding and to access an imprint or further informations. Usage is logged into files to provide a basis for extracting statistical information about the usage. The details about the exhibits are presented as images and as such impose no limit to the design choices made by the content provider or exhibition designer. The application (enhanced with a panoramic view) has been integrated successfully into a large special exhibition about the ancient city of Pergamon 2011/2012 at the Pergamon Museum Berlin within the interdisciplinary project "Berlin Sculpture Network".}, language = {en} } @inproceedings{ProhaskaHegeGiehletal.2003, author = {Prohaska, Steffen and Hege, Hans-Christian and Giehl, Michael and Gowin, Wolfgang}, title = {A Virtual Laboratory for Assessment of Bone Biopsies}, booktitle = {14th IAA Humans in Space Symposium}, address = {Banff, Alberta, Canada}, pages = {7}, year = {2003}, language = {en} } @inproceedings{SaparinGowinZaikinetal.2003, author = {Saparin, Peter and Gowin, Wolfgang and Zaikin, Alexei and Thomsen, Jesper and Prohaska, Steffen and Hege, Hans-Christian and Kurths, J{\"u}rgen}, title = {Quantification of Changes in Spatial Structure of Human Bone Biopsies Using 3D Measures of Complexity}, booktitle = {14th IAA Humans in Space Symposium}, address = {Banff, Alberta, Canada}, year = {2003}, language = {en} } @inproceedings{ProhaskaHegeGiehletal.2003, author = {Prohaska, Steffen and Hege, Hans-Christian and Giehl, Michael and Gowin, Wolfgang}, title = {Interactive Visualization to Support Quantification of Bone Biopsies}, booktitle = {2nd European Congress 'Achievements in Space Medicine into Health Care Practice and Industry'}, address = {Berlin-Adlershof}, year = {2003}, language = {en} } @inproceedings{SaparinGowinZaikinetal.2003, author = {Saparin, Peter and Gowin, Wolfgang and Zaikin, Alexei and Prohaska, Steffen}, title = {Quantification of changes in human bone structure at different skeletal locations using measures of complexity}, booktitle = {2nd European Congress 'Achievements in Space Medicine into Health Care Practice and Industry'}, address = {Berlin-Adlershof}, year = {2003}, language = {en} } @inproceedings{GowinSaparinProhaskaetal.2003, author = {Gowin, Wolfgang and Saparin, Peter and Prohaska, Steffen and Hege, Hans-Christian and Belle, Stefan and Felsenberg, Dieter}, title = {Architectural Reasons for the Femoral Neck Fracture Location}, booktitle = {2nd European Congress 'Achievements in Space Medicine into Health Care Practice and Industry'}, address = {Berlin-Adlershof}, year = {2003}, language = {en} } @inproceedings{ZaikinSaparinProhaskaetal.2003, author = {Zaikin, Alexei and Saparin, Peter and Prohaska, Steffen and Kurths, J{\"u}rgen and Gowin, Wolfgang}, title = {2D and 3D bone modelling for analysis of changes in the bone architecture and for evaluation of structural measures.}, booktitle = {2nd European Congress 'Achievements in Space Medicine into Health Care Practice and Industry'}, address = {Berlin-Adlershof}, year = {2003}, language = {en} } @inproceedings{ThomsenKollerLaibetal.2003, author = {Thomsen, Jesper and Koller, Bruno and Laib, Andreas and Prohaska, Steffen and Giehl, Michael and Gowin, Wolfgang}, title = {Comparison between Static Histomorphometric Measures Conducted by Traditionally 2D Histomorphometry and 3D μ-CT in Human Tibial Biopsies}, booktitle = {2nd European Congress 'Achievements in Space Medicine into Health Care Practice and Industry'}, address = {Berlin-Adlershof}, year = {2003}, language = {en} } @inproceedings{HegeWeinkaufProhaskaetal.2004, author = {Hege, Hans-Christian and Weinkauf, Tino and Prohaska, Steffen and Hutanu, Andrei}, title = {Distributed visualization and analysis of fluid dynamics data}, booktitle = {Proc.

The presented methods are implemented by an image processing pipeline that determines pore centers, pore paths and pore constrictions. These pore space elements build a graph that represents the topology of the pore space in a compact way. The representations we derive from μCT image data of realistic soil specimens enable the computation of many statistical parameters and, thus, provide a basis for further visual analysis and application-specific developments.

This is achieved by combining automatic methods, visual validation, and interactive correction. After an initial alignment, the user can continuously improve the result by interactively correcting landmarks or matches of filaments. Supported by a visual quality assessment of regions that have been already inspected, this allows a trade-off between quality and manual labor. The software tool was developed to investigate cell division by quantitative 3D analysis of microtubules (MTs) in both mitotic and meiotic spindles. For this, each spindle is cut into a series of semi-thick physical sections, of which electron tomograms are acquired. The serial tomograms are then stitched and non-rigidly aligned to allow tracing and connecting of MTs across tomogram boundaries. In practice, automatic stitching alone provides only an incomplete solution, because large physical distortions and a low signal-to-noise ratio often cause experimental difficulties. To derive 3D models of spindles despite the problems related to sample preparation and subsequent data collection, semi-automatic validation and correction is required to remove stitching mistakes. However, due to the large number of MTs in spindles (up to 30k) and their resulting dense spatial arrangement, a naive inspection of each MT is too time consuming. Furthermore, an interactive visualization of the full image stack is hampered by the size of the data (up to 100 GB). Here, we present a specialized, interactive, semi-automatic solution that considers all requirements for large-scale stitching of filamentous structures in serial-section image stacks. The key to our solution is a careful design of the visualization and interaction tools for each processing step to guarantee real-time response, and an optimized workflow that efficiently guides the user through datasets.}, language = {en} } @misc{KnoetelSeidelZaslanskyetal.2017, author = {Kn{\"o}tel, David and Seidel, Ronald and Zaslansky, Paul and Prohaska, Steffen and Dean, Mason N. and Baum, Daniel}, title = {Automated Segmentation of Complex Patterns in Biological Tissues: Lessons from Stingray Tessellated Cartilage (Supplementary Material)}, doi = {10.12752/4.DKN.1.0}, year = {2017}, abstract = {Supplementary data to reproduce and understand key results from the related publication, including original image data and processed data.
