I do image processing, and right now I need to resample some images taken from slightly different perspectives so I can match up features. The pixel intensities have scientific significance, so I want to do something that will preserve local flux and not "miss" anything. What I want to do is exact area resampling, as discussed here:
Except the coordinate change I'm doing is not just a translation; at the very least it involves translation, rotation, and perspective change.
I can't find anything on file exchange or by googling. Any ideas?
