Segmentation Algorithm [message #18031]

Dear all,

I'm new to IDL and as such I hope you excuse my ignorance. My problem is
not really a problem but more of a question really. We've been trying to
develop an application which reads in stacks of Magnetic Resonance
Images (i.e. volume data) and then binarizes the image to leave only the
required identifiable structure and from it generates a 3D STL surface
file.

For this we use SEARCH3D, but unfortunately this uses the Marching Cubes
algorithm, which is not very good (i.e. not a smooth surface) or
economical generating polygons. Is there any other available algorithm
for this in IDL?

The "growing balloon" algorithm would be ideal for this, but we found no
mention of it on the documentation. Anyone has tried to implement this
before? I much more experienced in C than I am in IDL, so I was hoping
someone had something similar already developed. If not... oh well!

Cheerio!
AL
