I just saw this too and would like to misuse this thread to suggest
another enhancement related to image processing you might consider: make
ndimage maskedarray aware. Unfortunately we don't have any money to
spend, otherwise I'd love to support this financially too. But it's a
thing I'm running into (ndimage not working with missing data, that is)
regularly, and for which it often is pretty hard to work out a
workaround. E.g. any of the resampling (ndimage.zoom) or kernel
filtering routines choke on array's with NaN's, and don't recognize
masked arrays. Alas virtually all of the image data I process (satellite
imagery) contains missing/bad data...
I know it probably will be a pretty involved task, as ndimage comes from
numarray and seems to be largely implemented in C. But I really wanted
to raise the issue now the image processing subject turns up once again,
and hope some folks with more/better programming skills than me might
like the idea...
Oh and I know of course ndimage is scipy, and this list is numpy. But as
the image processing subject emerged here, well...
