Write-up submission deadline:
Monday, Mar 9, 10 am

Contents: The importance of 3d data has grown enormously in the last decade, be it for cinemas, digital cameras, computer games or medical applications. The goal of this seminar is to discuss recent advances in the field of surface processing as well as to understand the mathematical concepts needed for this. Possible topics include

  • basic concepts from differential geometry,
  • representation and discretisation of 3d surfaces,
  • reconstruction of surfaces from point clouds,
  • diffusion-based surface smoothing,
  • simultaneous mesh editing
  • and many more.

Prerequisites: The seminar is for advanced bachelor or master students in Visual Computing, Mathematics or Computer Science. Basic mathematical knowledge (e.g. Mathematik für Informatiker I-III) is required, and some knowledge in image analysis or geometric modelling is recommended.

Language: All papers are written in English, and English is the language of presentation.

The registration period is over.

Since the number of talks is limited, we ask for your understanding that participants will be considered strictly in the order of registration – no exceptions.

Regular attendance: You must attend all seminar meetings, except for provable important reasons (medical certificate).

Talk: Talk duration is 30 min, plus 15 min for discussion. Please do not deviate from this time schedule.
You may give a presentation using a data projector, overhead projector or blackboard, or mix these media appropriately. Your presentation should be delivered in English. Your slides and your write-up, too, should be in English.

Write-up: The write-up should summarise your talk, about 5 pages per speaker will be adequate in most cases. Electronic submission is preferred. File format for electronic submissions is PDF – text processor files (like .doc) are not acceptable. Do not forget to hand in your writeup, because participants that do not submit a writeup cannot obtain the certificate for the seminar!

Plagiarism: Adhere to the standards of scientific referencing and avoid plagiarism: Quotations and copied material (such as images) must be clearly marked as such, and a bibliography is required. Otherwise the seminar counts as failed.

Mandatory consultation: Talk preparation has to be presented to your seminar supervisor no later than one week before the talk is given. It is your responsibility to approach us timely and make your appointment!

No-shows: In case you do not appear to your scheduled talk, we reserve the right to exclude you from all future seminars of our group.

Participation in discussions: The discussions after the presentations are a vital part of this seminar. This means that the audience (i.e. all paricipants) poses questions and tries to find positive and negative aspects of the proposed idea. This participation is part of your final grade.

Being in time: To avoid disturbing or interrupting the speaker, all participants have to be in the seminar room in time. Participants that turn out to be regularly late must expect a negative influence on their grade.

We plan to discuss the following papers. If your registration was successful, the password will be sent to you before the first meeting.
