Thats great news.

I'm working on a pairwise optimisation stuff, using pano12. this
should make it feasible to automatically optimise complicated panoramas,
because a good initialisation for the global optimisation will be provided.

Putting all this together should lead to a "drop pictures, get pano"
application, with perserving all manual editing possible with hugin/pano
tools.

Ok, I've done just that, here are the results:

(needed to convert to pgm grayscale, used imagemagick for that)

-------------

island.wh-wurm.uni-ulm.de$ convert 2181_resize.jpg test.pgm
island.wh-wurm.uni-ulm.de$ keypoints < test.pgm  > test.keypoints
Finding keypoints...

island.wh-wurm.uni-ulm.de$ time keypoints < test.pgm  > test.keypoints
Finding keypoints...
3679 keypoints found.

real    0m19.184s
user    0m18.310s
sys     0m0.740s

---------------

Thats on a 700 Mhz pentium3 machine. 

I'll send you the results in a separate mail.

ciao
  Pablo
