each cell as initialization. Our algorithms are evalu-
ated on a set of 5 images with cells of a human hep-
atoma cell line, each composed of three channels la-
beling nuclei, SGs and PBs, respectively. The results
clearly show the benefits of the cascaded approach as
the overall segmentation quality is high. This is true
as well for precision and recall of cell areas as for the
assignment of particles to their corresponding cells.
Future work will include improvements of nucleus
segmentation to avoid or correct fusion of neighbor-
ing nuclei. Furthermore, data-depended adaption of
the number of levels used in the cascaded approach
with an appropriate stopping criterium will be scruti-
nized.
