Here is some advice on segmentation.
When you first start using an algorithm, the best way is to visualize
the algorithm in action. So you need to use a program that allows you to
do that. Once you have figured out all the parameters you can use
command line programs!
I would suggest the SNAP program, it is part of InsightApplications and
it has a few version of level set implemented. You can open up your
image place your seed and see how it works. It has a few cool features
that allows you to preview the edge image and so on. (read the tutorial)
good luck
Leila
