[SciPy-User] info scipy.ndimage.filters.maximum_filter

[David Pine]

Emmanuelle,

Nifty trick with IPython to see the wrapper.  Thanks for the tip.

I found the C code on the web -- on the "SciPy Dev Wiki" -- but I was unable to locate it on my computer.  I use the Enthought distribution for the Mac.

Thanks again.

Dave

I can figure things out from that.  It seems odd to me that the there seems to be no link to the source code for these routines on the SciPy documentation site.
