[SciPy-User] watershed

[dlibyp at gmail.com]

Hi all,
My question is a digest code question, so that I post on scipy-user, 
please tell me if I should no more do that.
I would like to see source code for watershed algorithm. Code in 
scipy.ndimage.measurements for watershed is a wrapper for method 
watershed_ift in _nd_image. Module is imported in measurements.py, but I 
cannot find it in parent repository.
Sorry for naive question: does _nd_image refers to C implementation of 
watershed_ift() method?
Thanks.
Rig
