Summer Term 2005

Differential Equations in Image Processing and Computer Vision

Dr. Bernhard Burgeth

Lectures (4h) with theoretical and programming exercises (2h)
(9 credit points)

Tuesday 14-16 c.t., Thursday 11-13 c.t., Building 45, Lecture Hall 003
First lecture: Tuesday, April 12, 2005


The registration is closed!

Theoretical and programming exercises take place in weekly alternation.
The exercises are supervised by Dr. Martin Welk.


Equally suited for students of mathematics and computer science. Requires undergraduate knowledge in mathematics (e.g. ''Mathematik für Informatiker I,II'') . Knowledge in image processing or differential equations is useful, but not required. The lectures will be delivered in English if requested.


Many modern techniques in image processing and computer vision make use of methods based on partial differential equations (PDEs) and variational calculus. Moreover, many classical methods may be reinterpreted as approximations of PDE-based techniques. In this course we will get an in-depth insight into these methods. For each of these techniques, we will discuss the basic ideas as well as theoretical and algorithmic aspects. Examples from the fields of medical imaging and computer aided quality control illustrate the various application possibilities.

Since this class guides its participants to many research topics in our group, its attendance is required for everyone who wishes to pursue a diploma or master thesis in our group.

Written Exams: Update !

The results of the written exam can be found here , finally!

The participants of the first written exam have the opportunity of inspecting their exam sheets on
Friday, September 16th, between 1:00 and 3:00 p.m., building 27.2, basement, room 26 (opposite ladies' restrooms).
Outside this time, individual inspection is possible upon appointment in the office of Bernhard Burgeth.

The second written exam has taken place on Tuesday, October 4th, 2005 in the afternoon, from 2:00 to 5:00 p.m. in Hörsaal I Mathematik (mathematics lecture hall), building 27.2
