Dear Curtis,

thank you very much for your immediate reply and beyond that the example
you adapted.

In my current FIJI I got this error
[ERROR] null
java.lang.ClassNotFoundException:
net.imagej.ui.swing.updater.ImageJUpdater .. (sort of strange)

But in a recent and fresh copy of FIJI it works fine, when following
your steps.

I played around with it a few times and recognised when simply closing
"Regions" and "Seeds" from the "blobs.gif"-Sample two times, on the
third run I start getting strange image results, which tend to become
worse every time.
Is this only on my machine like this or probably BoofCV-related?

Ahoy,
Rainer
