Please direct all organisatorial requests to Andrés Bruhn.

Contents: Many problems in image processing and computer vision require the use of efficient numerical algorithms. In this seminar the participants learn more about a selection of successful algorithms that are frequently used in applications. This includes

• B-tree triangular coding

• orthogonal transformations (FFT, FWT, FLT)

• approximation methods (least squares, total least squares, SVD)

• fast iterative solvers for linear systems

• minimisation of convex and nonconvex functionals

• efficient algorithms for diffusion filtering

• algorithms for TV regularisation

• algorithms for continuous-scale morphology

• implementations on special hardware (GPUs, mobile phones)

Prerequisites: The seminar is designed for graduate students (i.e. advanced Bachelor, Master, and post-Vordiplom) of visual computing, computer science or mathematics. Specific knowledge in image analysis or numerical methods is useful but not required.

Language: Understanding scientific text in English is indispensable. Talks and write-up can be in English or German.

Sign-up: If you are interested to participate, please sign up by e-mailing to bruhn@mia.uni-saarland.de not later than Tuesday, February 13, 2007. Please include your name, student ID (Matrikelnummer), date of birth, study program, and valid e-mail address.
Since the number of talks is limited, we ask for your understanding that participants are considered strictly in the order of incoming e-mails – no exceptions.

Sessions: First meeting takes place Wednesday, February 14, 2007, 16:15h, Bld. E1.1, room 306. Regular sessions will be weekly during the summer term. Exact schedule to be determined at first meeting.

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.

Write-up: The write-up 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 your 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!

NEWS: The cerfificates (Scheine) are issued by the office of the Mathematics Department. They can be obtained from Mrs. Voss, Building E2.4, Room 111 (math building, ground floor, 8.15-11.30 AM).
