morphological image processing in Python

[Alexandre Fayolle]

Hello,

I'm about to start a project which will involve some greyscale image
processing using morphological operators (erosion, dilation, distance
transforms...), and I was wondering if these operators were available in
Python through some open source libraries. 

A quick google search returned pymorphpro[1], which is unfortunately not
free software, and there also seem to be something available in ITK [2].
Unless I'm mistaken, the PIL does not provide these operations, nore do
Numeric/numarray/scipy. 

Have I missed the one true Python mathematical morphology toolbox?

Thanks in advance for any advice.
