    Abstrakt: The present biomedical research increasingly relies on automated
    processing and analysis of large amount of image data. Two fundamental tasks in
    this area are automated cell segmentation and tracking. The task of cell
    segmentation is to split the image into several disjoint regions, each
    accurately outlining every single cell. The task of cell tracking is to link
    together the regions that represent the same cell in a time-lapse image
    sequence. This allows for time-resolved quantitative description of events and
    changes in displayed cell behaviour. Needless to say, the accuracy of the two
    tasks influences accuracy of the consequent biological analysis.

    This talk will be focused on ways to evaluate performance quality of
    segmentation and tracking algorithms. In particular, I will review the
    evaluation protocol implemented in the Cell Tracking Challenge, an international
    benchmarking initiative that FI MU is part of, and identify current challenges
    in the field. Last but not least, I will give an outlook on a artificial image
    synthesis, which I see as a prospective way to foster the future development in
    the field.
