Image processing, modeling and simulation

Coordinator: Stefan Kunis

Research field D is devoted to the development of algorithms and methods within the framework of biological problems in close collaboration of mathematicians, physicists and cognitive scientists. Aims include the

  • quantitative evaluation and visualization of data from advanced imaging techniques
  • identification of causality and correlations in complex data sets
  • mechanistic description of molecular processes up to complete microcompartments.

Neurophysiological basis of cognitive functions - Visual processing and embodied cognition

The research group of Peter König investigates multisensory integration and sensorimotor coupling with a variety of experimental and theoretical methods. This includes on one hand the quantitative analysis of subjective perception, eye tracking, EEG, MEG and fMRI.  Furthermore, modeling of neuronal systems in the contest of embodied perception and processing of natural stimuli by neuronal networks and hierarchical Bayes models. In close interaction of experimental and theoretical work hypotheses are tested and successively refined. Results of this work are, as far as possible, translated to real world applications and have initiated founding of two spin-off companies.

Image processing and visualization of complex multidimensional data

Complex multidimensional image data sets need a well-balanced post-processing strategy before an appropriate 3D visualization is feasible. We provide diverse tools for image deconvolution as well as volume and surface rendering in order to visualize dynamic processes at highest contrast. Furthermore, we develop tailored image processing tools for diverse scientific problems (protein co-localization, quantification of morphological changes, feature segmentation, etc.). Our aim is to integrate these tools into well-established software such as ImageJ or Matlab to increase usability and to extend user group.

Signal propagation across biological membranes  - Surface architectures for quantitative interaction analysis

For the analysis of images obtained by single molecule localization microscopy, the Piehler group has developed an integrated evaluation software. Next to the rendering and analyzing single molecule localization-based superresolution images, the characterization of diffusion dynamics and interactions by spatial and spatiotemporal correlation techniques is a particular focus of this work. In collaboration with the Kunis group, these efforts are pushed towards implementing fast 3D superresolution imaging in living cells by single molecule localization and structure illumination.
