Hello:
Thanks for the previous messages.
I have checked out the snake stuff. I do not think I want such a
complex thing.
What I want is that I shall specify a region to the routine and it
shall try to fill regions having the intensity of the specified
region. The IDL has a built-in that uses standard deviation and
thresholding.
Is there any way we can improve on this ? Since there tend to be
discontinuities in the region, the snake may sometimes stop following
the region, although it hasnt quite finished the job.
Thanks
Pravesh

I've always found SEARCH2D to be helpful, although I guess
it is replaced now by the more powerful REGION_GROW. You
might also want to explore Active Contouring (or Snakes),
which can also be helpful with these MRI images:
