I'm currently working as a research scientist at the Institute of Imaging and Computer Vision, RWTH Aachen University.

My research interests are for example

  • Identification of imaging systems (OTF measurement, Radiometric calibration, Camera calibration, non linear camera transfer function)PSF/MTF, Color filter, Non-linearity, Noise characteristics

  • Segmentation (Mean shift segmentation, Model based region grouping, ...)

  • Segmentation evaluation

  • Multiscale analysis, Wavelets

  • Deconvolution, 3D-Deconvolution

  • High-dynamic-range imaging

As well as the application of such methods for the early cancer diagnosis based on microscopic images of cell specimen. For example:

  • High dynamic range microscopy (HDR microscopy)

  • Segmentation of silver stained nuclei

  • Detection of AgNORs in silver stained Nuclei

  • Quantification of immuncytochemical stained cytopathological specimens
