Semantic Modeling and Acquisition for Urban Safety Simulations
This project aims at analysing the traffic flow of open roads in real time by a sensor fusion of radar data with video feeds. Radar gives an accurate position and velocity of vehicles making computer vision methods more robust in computing their spatial extent and classification from video streams. In this way the huge amount of raw data is reduced to semantically relevant information, which is highly memory efficient, anonymous and sufficient to reconstruct traffic flow over long time periods. Another important goal is a sophisticated 3D visualization of the reconstructed traffic flow providing interactive tools for visual analysis. Information obtained in this way will significantly contribute in adopting measures to increase traffic safety. ![]()

Scenario Pool: Visual Analytics for Action Planning in the Presence of Uncertainty
Natural hazards such as floods are likely to occur more often in the near future. Modern information technology can simplify the workflow of disaster management. However, none of the existing tools is tailored to the requirements of action planning. The major challenge lies in the sheer quantity of complex information the planner has to account for. The choice of the right action at the right time depends on a variety of factors and cannot be automated. Moreover, since the course of events cannot be exactly predicted, numerous, alternative scenarios have to be considered. This project is dedicated to research in the field of Visual Analytics for the development of a novel decision-support system with two major goals in mind: First, users will be able to create a large scenario pool without the need for engineering skills. Second, first responders will be empowered to exploit this scenario pool for decision making in time-critical situations. ![]()

KASI: Knowledge Assited Sparse Interaction for Peripheral CT
The knowledge assisted sparse interaction proposed above is a general paradigm, applicable to any area of visualization. However, within the framework of the current proposal we want to specialize predominantly on one of these possibilities, namely on the processing and diagnostics of the peripheral artery occlusive disease (PAOD) within the context of noninvasive CT angiography [1]. PAOD is a significant health problem in the industrialized world, with a prevalence of 8-12 million cases in the US alone [32]. The number of such cases is expected to increase as the population ages. ![]()

ViMaL: A Visualization Mapping Language
Visualization is the discipline dealing with the depiction of data. The assignment of visual abstractions to data abstractions is referred to as the visualization mapping. Expressive visualization mappings proofed in many cases to be more effective than the examination of raw data (i.e., large tables of numbers). Although visualization mapping is a crucial step in the visualization pipeline surprisingly few general approaches exist. We propose to develop the Visualization Mapping Language (ViMaL) that is capable of describing expressive visualization mappings and provides user interfaces suitable for non-experts in visualization. ViMaL will be a language that is used to specify visualization pipelines. We will provide language concepts for the specification of data abstraction processes, visual concretization processes and the required visualization mapping. With this approach the semantics of a specific domain are modeled by the domain experts while the semantics of the visualization domain are modeled by the visualization expert. The visualization mapping is described using domain semantics as well as visualization semantics. Unlike other general purpose visualization systems, ViMaL systems explicitly use the semantics of the visualization mapping process. It incorporates information and knowledge assisted methods in the visualization mapping pipeline. In the scope of this project we will define a novel Visualization Mapping Language and implement a toolbox that aids researchers from other areas to integrate the ViMaL concepts into their systems. The toolbox will provide basic ViMaL document setup and parsing as well as components for each step in the visualization pipeline. We will make use of fuzzy logic in our components for the abstraction of data, for the visual concretization, and for the visualization mapping. We believe that the formalization of the visualization pipeline that is achieved with the visualization mapping language will enable many researchers from other domains to benefit from existing visualization methods. Further, the introduction of domain and visualization semantics for the specification of visualization mappings enables meta-visualization approaches that provide insight into the visualization process itself. Laypersons will benefit from such meta-visualization systems that are able to illustrate the involved components. ![]()

Smart-CT: Genaue Geometriebestimmung und Interfacecharakterisierung von Multi-Materialbauteilen mittels Kegelstrahl-CT
Die Vermessung der 3D-Geometrie und von inneren Grenzflächen (z.B. Materialübergänge, Porennester, Inhomogenitäten,¿) von industriellen Objekten wie z.B. Multimaterial und Verbund-werkstoffkomponenten ist integraler Bestandteil moderner Bauteilentwicklung und Qualitätssicherung. Üblicherweise wird die Geometrie taktil mittels Koordinatenmessgeräten an vordefinierten Punkten gemessen. In speziellen Fällen wird die taktile Messtechnik mittels optischer Scanner unterstützt. Allerdings können beide Messverfahren nicht innere Geometrien oder Materialübergänge erfassen. Um diese Nachteile zu eliminieren, wird in letzter Zeit immer häufiger Röntgen-Computertomografie (CT) verwendet. Hierbei wird meist 3DCT eingesetzt (=CT mit einer Kegelstrahl-Röntgenquelle und einem Matrixdetektor), die wegen der signifikant kürzeren Messzeiten und der damit verbundenen Kostenersparnis für die meisten Anwendungen attraktiver ist als konventionelle 2DCT (=CT mit einer Fächerstrahl-Quelle und einem Zeilendetektor)[CT08, PTB07, DIR07, DIR03, SS00]. CT ist eine zerstörungsfreie Methode, mit der Bauteile dreidimensional vermessen werden und versteckte Fehler (z.B. Lunker, Risse, Verunreinigungen, Poren, Materialfehler, Materialübergänge,...) in der Tiefe eines Werkstoffes detektiert werden können. Das Verfahren der CT ist seit vielen Jahren in der medizinischen Diagnostik etabliert und hat in jüngster Zeit sehr stark an Bedeutung in der Industrie gewonnen. Der Fokus dieses vorgeschlagenen Projekts liegt im Bereich der 3DCT für industrielle Anwendungen. Für alle weiteren Ausführungen wird CT in diesem Kontext betrachtet. ![]()

AutARG: Automatic Algorithms for Result Generation in Visualization
The main goal of the proposed Dissertation Fellowship project AutARG (Automatic Algorithms for Result Generation in Visualization) is to speed up the analysis process of 3D/4D simulation data from different domains like engineering, meteorology, climatology, or medical applications. Since the number and size of simulations in these fields is increasing rapidly fewer and fewer time can be spent in the actual analysis process of the generated data. We therefore want to introduce novel approaches to semi-automatically generate visualization and analysis results based on user-defined templates, rules and semantic information gathered during previous interactive analysis sessions. This will greatly improve the efficiency of the post-processing phase necessary to document and present information gained from the simulation results. In the course of this project we plan to research efficient and user friendly methods for the analysis and presentation of simulation results, which will be implemented in the SimVis framework. SimVis is a state of the art interactive visual analysis tool for large and complex simulation data, which up to now, like many other state of the art systems, is relying mostly on time-consuming user interaction. The planned project will be structured into three larger phases of research and development. In the first phase automatic generation of visualization results based on manually specified features will be introduced. The second phase will deal with semi-automatic feature specification based on templates additionally to the automatic result generation. The third phase should extend the proposed methods to incorporate story telling functionality which can be used to present results to non-experts. The results of this project will not only include the PhD thesis of Philipp Muigg and a larger number of high-quality publications, but also newly developed software modules, which shall be capable of demonstrating the full potential of the newly developed methods also for real world datasets from various application fields. ![]()

TERAPOINTS - High Quality Visualization and Interaction with Gigantic Point Data Sets
Laser scanning is an important tool in cultural heritage for documenting the state of archaeological monuments. The data produced by laser scanning is ever increasing, with the latest generation of laser scanners generating a billion of points in one measurement pass. To colorize the laser scans, additional photographs are taken. Managing these huge amounts of data in terms of size is a challenge on its own, but also to ensure the quality of the resulting point-based models is of utmost importance for the further development of laser scanning as a standard technique in cultural heritage. We identified three topics that can drive forward the integration of laser scanning in the everyday work of archaeologists. ![]()

General Purpose Visibility
Visibility culling is a fundamental problem of computer graphics, and is of crucial importance for many applications, like game development or architectural design. For example, interactively rendering a model containing hundreds of millions of polygons like the Boeing 777 model shown on the cover page is only possible when invisible parts of the model are "culled" away. Solving the visibility problem has been an important research topic for many years, and countless methods have been proposed. Amazingly, most approaches still have more or less serious issues that prevent their widespread use. Preprocessed visibility solutions attempt to solve the problem in an offline step, but are often slow, lack robustness, and are hard to implement. Online culling algorithms have a lot of potential since they can be used on arbitrary scenes, but they induce an overhead during rendering which is unacceptable for applications that strive for optimal performance. We believe that basic research problems remain unsolved until this day for preprocessed visibility as well as for online culling, and the goal of this project is to tackle and solve the majority of these problems. In order to do this, we have to gain more insight into the complex properties of visibility, which are still not entirely understood. Our proposed methods have applications in various fields, like game development, architectural design, urban visualization, or massive model visualization. ![]()

Sim-CT: Simulation of an industrial 3D computer tomograph
Die Röntgen-Computertomografie (CT) ist eine sehr gut etablierte Methode in der Medizin, die in den letzten Jahren immer mehr in der Materialforschung und Industrie zum Einsatz kommt. CT ist eine zerstörungsfreie Methode, um Bauteile 3-dimensional zu vermessen und um versteckte Fehler (Risse, Verunreinigungen, Poren,.) in der Tiefe eines Werkstoffes zu detektieren. Bei einem modernen 3D-CT System mit einem a-Si- Matrixdetektor (amorphes Silizium) wird die Qualität der Ergebnisse erheblich von den Messparametern (Röhrenstrom- und Energie, Filter, Position des Messobjektes,.) bestimmt. Diese Einflußgrößen äußern sich in Form von mehr oder weniger stark auftretenden Messartefakten, die das Ergebnis verfälschen können. Bis zu einem gewissen Grad können Artefakte durch Korrekturalgorithmen verringert werden. Diese Korrekturverfahren sind nach wie vor Gegenstand der aktuellen Forschung und sind für 3DCT- Systeme noch nicht in der Praxis brauchbar. Ziel dieses Projekts ist es, Grundlagen für eine vollständige Simulation eines industriellen 3DCTs zu erarbeiten, wenn Geometrie und Material des Messobjektes bekannt sind. Damit können schon vor der CT-Messung die optimalen Messparameter bestimmt und die Artefaktkorrektur durchgeführt werden. Die Projektergebnisse führen zu folgenden Vorteilen: - Besseres Verständnis über das industrielle 3D-CT-System und der Wechselwirkung der Strahlung mit den Einzelkomponenten (insbesondere Werkstück und Detektor) - Verbesserung der CT-Messergebnisse, Reduktion von Artefakten und Fehlmessungen - Ausweitung der Anwendungsfelder von 3D-CT, Erhöhung der Messgenauigkeit ![]()

Visual Computing in Fundamental, Academic and Applied Science and Research
Visual Computing is an emerging field of research, formed by the progressive fusion of traditionally separate scientific fields. Visual Computing deals with problems that are focused on processing or acquisition of graphical data. Most visual computing researchers work in the fields of computer graphics, digital image processing, pattern recognition, visualization and virtual reality. Since many new technologies and problems require expertise in several of these fields, research groups increasingly look for opportunities to improve their cooperation with neighboring fields. Austrian, as well as Russian research groups have ample experience in several of the fields that comprise visual computing, and have published high level results of their research. Following a successful seminar in Vienna last year, the Joint Seminar on Visual Computing in Fundamental, Academic and Applied Science and Research would give an opportunity for researchers of both countries to present their results to a larger audience of experts, to identify common problems and to participate in an open dialogue that may form the basis for future cooperative projects. The Seminar will mainly consist of presentations from all participants, dealing with topics from all areas of visual computing. Additionally, the seminar will include several keynote speakers, research facility tours and social events. ![]()

EU U-CREATE, Creative Authoring tools for Edutainment Applications
U-CREATE is initiated by Alterface, Imagination and ion2s, three SMEs which are primarily active in the field of edutainment, i.e. the joining of education and entertainment (customers are museums, cultural institutions, entertainment parks¿) They share a common and important problem: efficient content creation. Be it interactive setups, Mixed Reality experiences, location-based services, all these technologies are worthless without content: content is always to be tackled or delivered at the same time as technology. However, content creation is a long process that can turn to nightmare when implementing large-scale projects. The solution is two words: authoring tool. A powerful, graphical, beyond the state-of-the-art authoring tool is needed that allows one to create elaborated contents in a fast and easy way. No such tool exists to date due to the highly innovative products commercialized by the SMEs. Such a tool will be created by the project. The authoring tool will increase competitiveness, because it significantly shortens production time (50% reduction of integration time) and effort (creation process affordable to non-specialists) for content development. It will also enable other people to create contents for the intended systems: SMEs can then sell more software while subcontracting or licensing the content production. It will also strengthen the European position in an authoring market dominated by US companies. SMEs alone cannot afford such a task, in terms of expertise but also in terms of resources. This project gathers the highly-specialized expertise from ZGDV, TUW and DIST which allows for the delivery of a prototype authoring tool. HadroNet will be the end-user serving the consortium and helping it to gather a larger community of end-users, in order to assess requirements, validate results and construct the basis of a commercial distribution system. Doing so, the project will set the first basis of a longer-term collaboration amongst all partners. ![]()
