24. Illustrative Medical Visualization
[Tietjen et al. 2005: Combining Silhouettes, Surface, and Volume Rendering for Surgery Education and Planning, In IEEE VGTC Symposium on Visualization, 2005, ]
Cel shading
Suggestive Contours
Silhouettes
Hatching
[Kai Lawonn, Tobias Mönch, Bernhard Preim: Streamlines for Illustrative Real-Time Rendering. Comput. Graph. Forum 32(3): (2013)]
Medical illustration use specific rendering techniques to show the important information in a meaningful and comprehensible way, which need not be photo-realistic. Among these methods are cel shading that provides a more cartoonish look of the region of interest. Contours and silhouettes enhance spatial cues and emphasize certain regions, while hatching can be used to provide better depth perception of occluding objects. All together, an illustration of the examined region should be provided.

25. Segmentation in Medicine
Vessel / Bone Segmentation
Thresholding
Active Contours
Vessel Detection
Threshold
Scale-Space
Segmentation is an important field in medicine in order to obtain the required information from the data. Various approaches exist for segmenting specific organs or regions of the human body. Among these are the segmentations of vessels and bones in order to create tailored angiographic visualization techniques. Others are the segmentation of the retina of the human eye. The detection of vascular structures and their corresponding centerlines and radius information is an important field in segmentation, depending on the applied vessel model (circular, elliptical).

26. Visualization of sports events
Sports Visualization
Visualization of sports events
Tracking events during sports meetings
Statistics and analysis
Sports meetings are not only entertaining, but usually also produce a huge amount of data. For coaches, sportsmen as well as for viewers, sports visualization techniques can help to get a better insight into this data. At the one hand, several statistical parameters are collected during a sports meeting, e.g. all given passes during a soccer game. Sports visualization techniques can help to further analyze this data. On the other hand, several actions and events are recorded during a sports meeting. Here time visualization techniques can help to create an overview of the current situation, and assisted coaches in their decision making.
Johanna Schmidt

27. Hierarchy Visualization
Datasets with hierarchical elements
Explore visualization possibilities
Explore interaction possibilities
Datasets may get very large
Many datasets contain a set of structural relations between different parts of the data set - typical examples are organizational charts, or library classification schemes. There are several possibilities on how this data can be visualized (like in a “family-tree”, in a radial layout, or as a treemap). One major problem with displaying hierarchies is that they can get very large and therefore hard to display. Within this topic, methods to visualize large data sets and their interaction techniques should be explored.
Johanna Schmidt

28. Visualization on Large Displays
Increase the amount of visible information
Display form factors
Interaction techniques
Perception
A common way to increase the amount of visible information is to utilize very large displays. Different display form factors and interaction techniques have been employed for various visualizations. But how do these presentation and interaction methods affect the perception of the visualized data? This seminar report should address the various hardware and software challenges, emerging interaction techniques, and perceptual aspects on large displays.
Manuela Waldner

29. Visualization on Mobile Devices
Visualization and Data Exploration on Small Mobile Devices
Visualization Techniques
Focus+Context
Interaction Techniques
New Application Areas
Mobile devices like tablets or mobile phones are now ubiquitous. While many applications have been successfully adopted for the small-scale portable devices, visualizing massive amounts of data is still an ongoing research challenge. This seminar work should report on existing mobile visualization solutions and which visualization and presentation techniques have been successfully employed to overcome the limited screen space. Also, it should explore potential interaction techniques and application areas that are not possible on traditional desktop interfaces, such as mobile augmented reality visualizations.
Manuela Waldner

30. Plagiarism Visualization
Text visualization techniques
Visualization of text comparison results
Plagiarism detection is an important process in academic environment. It helps to ensure that the grades are issued under the same conditions for all students, and that noone has an unfair advantage over the others. Visualization algorithms can be a great help in the process of detecting plagiarism. The state-of-the-art report should focus on various techniques how text, in particular text comparison results, can be visualized to aid plagiarism detection.

31. Visualization Systems
Visualization tools
Libraries
Plug-in architectures, data-flow networks
Scientists from many fields often need to visualize their data. However, they are not visualization experts. They need tools and modular systems which do the job for them. There are many visualization systems with different architectures, tailored for different type of users, tasks, or data. The state-of-the-art report should focus on existing visualization systems, describe their plug-in architectures, modularity, and what are they used for.

32. Volume Editing & Annotation
Live Wire \ Surface
Graph cuts
Reeb Graphs
Volume editing is challenging task with a wide field of application. Just imagine that without proper tools any detail should be explicitly drawn by people. For example, volume editing may be used in medical image processing. Doctors still use simple brushing to obtain masks of desired organs. Nowadays a lot of techniques are proposed for volume editing, making their life easier. Probably you’ve already used Smart Scissors and Live Wire in 2D. And there are even better solutions for interactive volume editing.

33. Physical-based manipulation Skeleton-based manipulation
Volume Manipulation
Physical-based manipulation
Skeleton-based manipulation
Feature-aligned manipulation
Volume manipulation is used for illustrative visualization and animation. Physical-based manipulation deals with specified properties of materials during manipulation, so results look quite realistic. For the purpose of animation skeleton-based manipulation is often used. There picking and moving logical segments of object is quite simple and yet efficient. To reproduce realistic appearance like in images in medical books during the surgery feature-aligned manipulation is used. This even allows to imitate behavior of real-world tools used in medicine like scalpels, retractors, peelers, dilators.
Alexey Karimov

34. Uncertainty Visualization
Positional uncertainty
Data uncertainty (errors)
Uncertainty representations
Volume rendering
Noise
Animations
Points with offset
…    
Every measurement has some degree of uncertainty or error associated with it. In many cases it is small and can be neglected. However, recently uncertainty is of high interest in many areas. Uncertainty visualization is a challenging task, as it takes additional data dimension to be shown to the user. Many visualization techniques depicting uncertainty of the underlying data have been developed: showing uncertainties with volume rendering, using noise or textures, utilizing animations, or using point point-based surface representations.

35. Parameter Visualization
Parameter exploration
Stability analysis (with respect to parameters)
Multi-dimensional data
Hyper slice
Parallel coordinates
Projecting parameter space    
Controlling algorithms behavior is done using many parameters. E.g., in engineering various simulations provide their outputs based on some physical parameters. Finding optimal parameters or exploring the sensitivity of the algorithm with respect to its parameters are important and elaborate tasks. The visual exploration is especially challenging as it often have to represent multi-dimensional data in the form that can be mentally perceived by humans. In this context parameter exploration systems are used. These systems are utilizing such techniques as parallel coordinates, scatter plots and a set of 2D parameter space projections.
Artem Amirkhanov

36. Molecular Visualization
Use of different representations
Real-time rendering
Visual analysis of cavities
Molecular structures can be represented by many different means. In the field of visualization such structures are often represented on 3D, in order to help the understanding of biological process. The state-of-the art should focus on the different techniques employed to visualize molecular structures, with a possible emphasis on real-time technique.
