Johan, On the Python side there is the ndimage package that is included in scipy (http://www.scipy.org/SciPyPackages/Ndimage) that has erosion and dilation functions that you might want to consider. Take a look at binary and grey scale morphology here: http://stsdas.stsci.edu/numarray/numarray-1.5.html/module-numarray.ndimage.h tml If they do what you need, then you can read an image into a numpy array using gdal,perform erosion/dilation, write a new image out with the result and rewrite extent and projection to the image.
