Noel, this sounds very interesting, but I cannot make it work in my setup.
I load the Clown image, then split into rgb and use the Red and Green as the
input. Then the first dialog comes up (asking for thresholds) and produces
the scatterplots.
The second dialog comes up and I reply "Manual", "Scatterplot logarithmic" and
"3" for the number of classes.
Here is where it seems to hang. A new "Segmented Zone" image appears (all
black" and nothing else.

If I use the Automatic mode, it only produces an output only when I check "Fix
sigma" (but I get 139 modes! rathen than the 3 I set).
What am I doing wrong?

I am using java 1.5.0_04 under suse linux 9.2 and IJ 1.35D.

Cheers,

Gabriel
