Color Segmentation w/ PIL?

[MooMaster]

I'm trying to write a Digital Image Processing program using the PIL
library, and upon consultation of the Handbook I see that it seems to
have built in functions to run Edge Detection (in the ImageFilter
module), but I don't see anything about Segmentation. Are there any
built-in tools to do this operation? Has anyone done this operation
with PIL in the past that can lead me in the right direction?

I don't know of any in Python, but an open source image processing package in
Java has been developed at Stanford University - http://www.gemident.net
GemIdent . GemIdent was originally designed to segment cells from
miscroscopic images and, more generally, can identify objects of interest
and do color image segmentation. Maybe some of the code can I apply to your
project and you can bridge the gap using Jython.

You might be interested in the ndimage module of scipy:

If you need a very serious image processing framework, ITK is might be very
interesting:

If so, have a look at the more Pythonic interface developed for it:
