rebin but ignore zero [message #62677] Fri, 26 September 2008 12:32

I have a very sparse array (image) and I want to resize it---shrink
it by a factor of 2 in each direction. If I do a rebin, every pixel
is
replaced by its nearest neighbor average, but many of those
neighbors are zeroes---not real zeroes, but zero because there
is no data there. This means, the resulting rebin-ed image has
values that are smaller than they "should" be.

Is there a way to do a rebin that can ignore these "blank" pixels?
