I don´t remember if you already told how you got your images. I
mean: are your individual pictures a copy of the movie frames? Do you
know some parameters of the lens used to make the movie?
As Hugin uses the lens geometry (image distortions, etc) I seems
sensible that nona could change yor values, as nona generates images
projected on a sphere (for panoramas) or over a plane, for mosaics --
which I guess is your problem: a planar surface with a field of
temperatures. [post note: I just checked your first message and you
told us about "/a temperature raster mosaic/"]. Have you seen
http://hugin.sourceforge.net/tutorials/scans/en.shtml already?
Did you create the control points by hand, or with cpfind or other
automated methods? Your hot surface has enough distinctive features to
select as controls points?
I apologize if those questions are already answered in previous
messages... I can´t remember it all ;)
