Brief C.V.


Björn Ommer is a full professor for Scientific Computing and leads the Computer Vision Group at Heidelberg University.

He has studied computer science together with physics as a minor subject at the University of Bonn, Germany. His diploma (~M.Sc.) thesis focused on visual grouping based on perceptual organization and compositionality.

After that he pursued his doctoral studies at ETH Zurich Switzerland in the Pattern Analysis and Machine Learning Group headed by Joachim M. Buhmann. He received his Ph.D. degree from ETH Zurich in 2007 for his dissertation "Learning the Compositional Nature of Objects for Visual Recognition" which was awarded the ETH Medal.

Thereafter, Björn held a post-doc position in the Computer Vision Group of Jitendra Malik at UC Berkeley.

He serves as an associate editor for the journal Pattern Recognition Letters. Björn is one of the directors of the HCI, a member of the extended board of directors of the IWR, principle investigator in the research training group 1653 ("Spatio/Temporal Graphical Models and Applications in Image Analysis"), and a member of the executive board and scientific committee of the Heidelberg Graduate School HGS MathComp. He has received the Outstanding Reviewer Award at ICCV 2015, CVPR 2014, ICCV 2013, CVPR 2011, and CVPR 2010. Björn has organized the 2011 DAGM Workshop on Unsolved Problems in Pattern Recognition.



Research Areas


Computer vision, machine learning, cognitive science, biomedical image analysis, and the digital humanities; esp.: visual object recognition in images and video, action recognition, shape analysis, graphical models, compositionality, perceptual organization and their applications.
