    Host: Dr. K. Marias


    In this talk, we give an overview of computer vision projects at the Computer Science Department, University of Hamburg. Two working groups are introduced: The Cognitive Systems Laboratory (KOGS) we are members of, and the Technical Aspects of Multimodal Systems (TAMS) group.

    From KOGS (http://kogs-www.informatik.uni-hamburg.de/), we introduce:

    • The VIGRA Library (Vision with Generic Algorithms), originally developed by Ullrich Kothe and now maintained at our lab: http://kogs-www.informatik.uni-hamburg.de/~koethe/vigra/
    • Segmenting Skin Cells from LSM Images, the PhD thesis of Christian-Dennis Rahn, supervised by Prof. H.-S. Stiehl
    • Segmenting Wood Fibres from ?CT Volumes, a small project working in collaboration with the departments of Wood Technologies and Physics of our University
    • CogVis Scene Interpretation (http://cogvis.informatik.uni-hamburg.de/), a large EU project dealing with scene interpretation.

    From TAMS (http://tams-www.informatik.uni-hamburg.de/), we show

    • The TAMS Service Robot (TASER), a mobile real-time system integrating the extraction and processing of information from multiple sensors and modalities.
    • The project "Automatic Manipulation of Atomic Structures in Hamburg (AMASH)" which integrates the "nanoManipulator", an advanced visualization interface using force feedback from the University of North Carolina with the ultra-high vacuum low-temperature scanning tunneling microscopes (UHV LT-STM) of the physics department in Hamburg. The long-term goal of this project is to automate the tedious manipulation processes.

    Finally, we give a short overview of our own thesis projects:

    • Hans Meine developed the GeoMap as a unified representation for both topological and geometrical aspects of a segmentation result. In his running PhD thesis, he extends this approach to sub-pixel accuracy and uses the framework to realize several automatic and interactive segmentation methods starting from an initial oversegmentation.
    • In her Diploma thesis, Verena Kaynig works on the evaluation and technical realization of several measures of geometric saliency within the GeoMap framework.


    Hans Meine (meine@kogs.informatik.uni-hamburg.de) received his Diploma in computer science at the University of Hamburg in 2003 (together with the MAZ award for the best Diploma of that term). His main research interest is topologically correct image segmentation with combinatorial maps. He is currently a PhD student and working as a scientific assistant at the cognitive systems group (KOGS) at the department of computer science, University of Hamburg.

    Verena Kaynig (kaynig@kogs.informatik.uni-hamburg.de) is currently working on her Diploma thesis at the same department and working group (KOGS); the topic is "perceptual criteria for edge relevance". She received her intermediate diploma in computer science in 2002.
