Image segmentation programs in IDL? [message #51897]

I am looking for image segmentation routines that are available in or
written in IDL. I think my images are not very challenging. They have
been thresholded, so that the regions I want to segment all have values
of -1, and the background is +1. The boundaries are smooth. Examples of
the images can be found about a third of the way down the page at
http://physics.kenyon.edu/people/sullivan/Research/CahnHilli ard/ .

I am aware of the particle tracking algoriths of Crocker, Weeks, and
Spalding, et al., but their problem is identifying same size circular
images and my objects vary in widely size and shape.

There is one complication that I can live without at first, but would
eventually need to rectify. My fields are have periodic boundary
conditions, so eventually I would like an algorithm that identified as
one object, an object that wraps around the top and bottom and left and
right sides of the image.

If I knew anything about image segmentation, I suspect this would be
easy. But I don't. Any help would be appreciated.
