"Commented too much"?  never ever :)

I played a little bit the imagej-plugin that you did provided - genereally i think it's great (espacially the youtube-link... if the plugin is cappable of doing the same: awesome!)
I just - i don't know wheter it is my stupidity or the sloweness of my pc - wasn't quite able to get good results. First of all: the plugin does take its time to check for circles, sometimes over 5 minutes. Is that normal Oo or schould i alter the parameters to start with (i always use the default ones, only chanching the size of the circle)
And another point: you were right: it cannot detect circles with holes. what it does is interpreting the leftovers as a great bunch of smaller circles - not were satisfying.

And when i transform the picutres above in binary style and let the macro run (the results above i got from picutres i transformed much more!) i just get nonsense :)

so far from me... how do i use teh macro correctly in my case?
