Hm, no, at least the colour correction seems to be in libpano
(adjust.c).

Sort of.  The colour adjustment is a very tricky thing, especially if
you are using (relatively) small-angle lenses: I have an 28mm
equivalent, which means I have to take in the order of 40 images for a
full pano.  Doing colour correction by hand then is an awful work...

ACK, but the idea behind the colour correction (histogram
equalisation) is nice.  I'd vote for either using/improving the one of
libpano, or include something ourself (or better yourself...
programming C isn't my thing, but I'dbe willing to help on algorithms)
