Greyscale + gaussian

I'll play around with that

In any case, thank you for all the great help you've provided!

Fred did not mention it but he does have a script that does some basic morphology methods (square kernel only). It is slower but that can be used to do the morphology steps.

As for the shape change, once you have located the 'larger' shape, you can use that to recover just that specific shapes area, and ignore the smaller ones.

Of course with full morphology you have access to non-square kernels, that would allow finding specific shaped areas, as distinct from other shapes. That is a key feature of morphology, though one I have not exampled very well.

my script is limited to 3x3 square kernel shape and one would have to use quite a few iterations to get the size effect one needs. it would have to be a post processing step to the previous commands or piped in to the script from the commands. see my morphology script at the link below. But I would be surprised if it worked on such an old version of IM without some modifications. But you can play with it and let me know what happens (what error messages you get).
