This is the home page of the Image Understanding and Pattern Recognition group at the University of Kaiserslautern. The group was headed from 2004-2014 by Prof. Dr. Thomas Breuel. 

Prof. Breuel started working at Google in 2014, but still supervising several students in the department.

Publications of the research group from 2004-2014 can be found on the Publications Page.


There will be some additional opportunities for oral exams in July or August 2014; that will be the last time Prof. Breuel will be offering exams. To schedule an exam, please contact secretary@iupr.com


Most inquiries should be directed to the Department of Computer Science; they will be able to give you additional contact information.


The following are links to course web sites for courses recently taught by Prof. Breuel; you may find them useful in preparing for exams.
