Dear tutors,
Given an image, I want to generate another image with the mean values of
the pixels in their neighbourhood, thereby ignoring some of the
neighbouring pixels (e.g. the padded boundary). I hoped I could use
masked arrays for that, but apparently, this does not work.
--
def fnc(buffer)
return numpy.mean(buffer)
mean = scipy.ndimage.generic_filter(masked_array, fnc, footprint = f, mode =
'constant', cval = 0.0)
--
Is there a way to get around this issue, or do I have to accept the filter
function can not handle masked arrays?
Thanks in advance!
Sincerely,
Koen
