You could enroll for a tutorial from Wed, Oct. 19, 2005, 23:00h until Sun, Oct. 23, 2005, 23:00h.

This course is suitable for students of mathematics or computer science. It counts either as a theoretical core course (Theorie-Stammvorlesung) in computer science or as an applied mathematics course. It is based on mathematical knowledge from the first two semesters. For the programming assignments, some elementary knowledge of C is required. The lectures are given in English.

Broad introduction into mathematically well-founded areas of image processing and computer vision. These fields are important in numerous applications including medical imaging, computer-aided quality control, robotics, computer graphics, multimedia and artificial intelligence. The classes qualify for starting a bachelor thesis in our group.
The lectures are continued in the summer term by the in-depth course "Differential Equations in Image Processing and Computer Vision" which leads to current research topics. Both classes are necessary in order to pursue a diploma or master thesis in our group.

The tutorials include programming and theoretical assignments. The programming assignments give an intuition about the way how image processing and computer vision algorithms work, while the theoretical assigments provide additional mathematical insights. The tutorials are conducted by Andrés Bruhn, Mahmoud Fouz, Christian Schmaltz, Ellen Schmeyer, and Oliver Vogel.

The written exam took place on February 21, 2006 at 2 PM.
A second exam will be offered on April 7, 2006 at 2 PM (until 5 PM).

NEWS: All students have the opportunity to improve their mark from the first exam in the second one. Only the BETTER mark counts.

Here is the distribution of places for the second exam:

Students ALBESSER - KAHL go to the MATH I lecture hall in building E2.5
Students KAISER - NGUYEN : MATH II lecture hall
Students NIKOLOVA - SCHEFER : MATH III lecture hall
Students SCHERBAUM - ZUKOWSKI : Computer Science building E13, lecture hall 2

Please do not forget to bring your student ID card with you.

The following thresholds were applied in determining the grades:

• grade 1.0 : 56 - 64 points
• 1.3 : 53 - 55
• 1.7 : 51 - 52
• 2.0 : 48 - 50
• 2.3 : 46 - 47
