Contents:
In this seminar, we will discuss a selection of research papers from the
last few years in the area of mathematical image analysis and computer vision.
The selected papers have in common that they introduce innovative ideas and
unconventional viewpoints into the description and processing of image data.
We expect that these approaches will be found in the centre of research in
mathematical image analysis during the years to come.
The variety of topics includes but is not limited to
nonlocal image filtering methods for texture
reconstruction, image denoising and image editing,
connections between partial differential equations and
waveletbased image filters,
modelling approaches for the integration of sensing and
processing,
a recent extension to sampling theory,
novel numerical schemes for differential equations with
applications in image processing.
Prerequisites:
The seminar is designed for graduate students (i.e. advanced Bachelor,
Master, and postVordiplom) of computer science or mathematics.
As mathematical prerequisites, completed MfI courses or equivalent
are necessary. Previous knowledge in image analysis methods is recommendable.
Language:
Understanding scientific text in English is indispensable. Talks
and writeup can be in English or German.
Signup: closed. The deadline was July 20, 2006. No free
capacity is left.
Sessions:
First meeting takes place
Friday, July 21, 2006, 16:15h (4:15 p.m.), Bld. E11, room 306.
Regular sessions will be during the winter term on
Wednesdays, 16:15h (4:15 p.m.), Bld. E11, room 306.
Participants who are hindered to attend a meeting for substantial reasons
should notify M. Welk in advance by email.
Regular attendance:
It is expected that you attend all seminar meetings, except for provable
important reasons (we check).
Talk:
Talk duration is 30 min, plus 15 min for discussion. Please do not
deviate significantly from this time schedule.
You may give a presentation using a data projector (»beamer«),
overhead projector or blackboard, or mix these media appropriately.
English is preferred as language of presentation; if you should decide to
talk in German anyway, you must use slides in English.
Writeup:
The writeup has to be handed in till the end of the lecture period. It
should summarise your talk, so some 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.
We recommend using LaTeX.
Adhere to the standards of scientific referencing: Quotations and copied
material (such as images) must be clearly marked as such, and a bibliography
is required.
Mandatory consultation:
Talk preparation has to be presented to seminar supervisor not later than
in the week before the talk is given.
It's your responsibility to approach us timely and make your appointment!
