General information
|
Goal:
The goal of this seminar is to write and present a state of the art report and to write a review on another report. A member of the teaching staff will guide and
help students in acquiring the scientific material and writing the report. The students are also expected to present their work in a 15 minutes talk.
Students will have the option to work alone or in groups of two.
Tasks for the students:
Teaching staff will evaluate and grade students based on the following output:
- A list of literature that a student intends to review. This document will be regarded as an official seminar registration of the student.
- Attendance of the lectures "Forschung und wie sie funktioniert" by Professor Eduard Gröller, the lecture "Wie halte ich einen Vortrag"
by Professor Werner Purgathofer, and the lecture "Wie schreibt man eine wissenschaftliche Arbeit" by Professor Michael Wimmer. You can ask for a waiver in case
you have already attended one of these talks.
- A written state of the art report in the form of a scientific paper. We strongly encourage that the reports are composed in LaTeX. The report must have
a minimum of 8 written pages (15-16 pages, if students are working in groups of two). The preferred language is English.
- A written review of one of the papers of another student.
- A 15 minutes presentation in English followed by a 10 minutes discussion. The slides are to be submitted to the teaching staff after the talk.
- Active discussion participation is expected after the presentation of other students.
Important Dates:
- Initial meeting on 05.03.2012 at 17:00 in the seminar room of the
institute 186 (Favoritenstr. 9-11 / 5.floor). In this meeting the topics will be presented and assigned to individual students or groups of students.
- Submit list of literature before 20.03.2012 to your supervisor. This will be regarded as the official acceptance of the topic and the official seminar registration.
- Attend the following lectures (they all take place in the seminar room of the
institute 186 (Favoritenstr. 9-11 / 5.floor):
- 26.03.2012, 15:30: "Wie schreibt man eine wissenschaftliche Arbeit", by Professor Michael Wimmer
- 17.04.2012, 16:00: "Wie halte ich einen Vortrag", by Professor Werner Purgathofer
- 24.04.2012, 17:00: "Forschung und wie sie funktioniert", by Professor Eduard Gröller
- Submit a first version of the written report to your supervisor before 17.04.2012. This report version will be used as a basis for the review task.
- Receive review form and report of another student on 18.04.2012.
- Submit the completed review form until 03.05.2012 to Johanna Schmidt
- Receive two reviews (one from your supervisor and one from another student) on 04.05.2012. Use the information provided in the reviews to update your report accordingly.
- Talks will be held on 22.05.2012 from 09:00 - 17:00 in the seminar room of the
institute 186 (Favoritenstr. 9-11 / 5.floor). Presence of the students is mandatory.
- Submit your final report until 29.06.2012 to your supervisor.
Plagiarism:
All the literature that is reviewed during the seminar has to be placed in the reference section of the report. You can have further information about referencing
here. We are all expected to abide by professional scientific ethics and make sure that the work is
not plagiarized in any sense.

Topics
|
- Uncertainty Visualizationtaken
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.
- Parameter Visualizationtaken
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 set of 2D parameter space projections.
- From the Smallest to the Biggesttaken
The visualization of the natural phenomena with scientific methods enables to experience the world that is otherwise limited to the human visual system. With the most advanced
microscopes and telescopes we are able to experience the world around us that would be hidden to us otherwise. If we look at the world at different scales, organized by size and
distance, we could build a scale. The goal of the project is to write a survey about visualizations that are made at those scale sorted from the smallest scale of picometer (scale
of diameter of a gold atom) to the scale of objects in the universe (distance to Quasar). The survey should contain description of methods currently used in science (capturing,
visual mapping, rendering) which should be accompanied with compelling images.
- Intangible Human-Computer Interfaces in Visualizationtaken
Standard ways of controlling computers are nowadays supplemented with novel methods that include computer vision, voice recognition and artificial intelligence. For example, after
Microsoft has released the Kinect to the market, first it got an attention of community of game developers and hackers, which was shortly joined by scientific audience from different
fields, as well. That resulted into several of novel applications ranging from games to medicine. The goal of the project is to write a report about alternative interfaces that control
interactive visualizations and so provide additional support to the user.
- Glyph based visualizationtaken
Glyphs are used to visualize certain information such as the orientation of flow, pressure or temperature. There exist several types of different glyphs like arrows,
ellipsoids or superquadrics. Each of them has its specific degrees of freedom or properties, onto which parameters, such as pressure or flow-orientation, can be mapped.
Some glyphs might convey this information well in 2D and others might be more suitable for 3D. Additionally, some glyph properties might be perceive differently, which leads
to the field of perception (pre-attentive stimuli vs. attentive stimuli).
- Data Acquisition Modalitiestaken
Data acquisition is a very important task. There exist several modalities that have different features and therefore are used in various application areas. Whereas one modality
is usually solely used, there are possibilities to combine different modalities in order to utilize their advantages. Nowadays, scanners are pretty fast and the radiation dose
has been decreased in order to not harm the patient's health. Some modalities might require some invasive procedure, such as CTA by injecting a contrast agent to enhance vessels.
- Graph Visualizationtaken
Data with tree- and graph-like structure are very common nowadays. For analysis of this kind of data it is crucial to be able to visualize it in a way that reveals areas of
interest. This means not only to assign visual properties to individual vertices and edges, but also create appropriate layout of the graph elements in 2D or 3D space.
- Comparative Visualizationtaken
Comparative visualization refers to the process of understanding how different datasets are similar or different. Such characterizations may occur at many different levels: image to image,
dataset to dataset, derived quantity to derived quantity, and methodology to methodology. Entire or subsetted datasets may be compared to one another. The interesting question here is how
comparisons should be visualised (rather than how the comparisons are calculated).
- Procedural Content Generationtaken
In the process of producing video games or movies it is sometimes necessary to create visual representations of objects which would be too laborious to be created manually by artists.
This is when the procedural content generation comes into play. Procedural content generation is a set of techniques for creating large amount of various visual content, such as 3D models
or textures, from small number of input parameters. It can be used to generate sceneries or even whole worlds for games and movies.
- Computer Graphics on Mobile Devicestaken
In recent years the graphics hardware for mobile devices gets better and better. Therefore it is possible to run complex renderings and visualizations. The report about this topic
should cover the various available graphics hardware for hardware (in tablets, mobile phones) as well as different APIs which are used from various platforms (Android, iOS, Windows, ?)
to implement the rendering pipeline.
