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.

Actually, numarray does support morphological array operations. See
the chapter on 'Multi-dimensional image processing' in the numarray
docs.

numarray

http://stsdas.stsci.edu/numarray/numarray-1.3.html/module-numarray.ndimage.html

This will be ported to the new scipy shortly. We could use some help.

Pymorph is a free.

Take a look at ADaM and it's python wrappers:
