In the cubicle of Bosch
Recently, some of my colleagues (not me, and I’m not entirely sure who) wallpapered the cube of one of my vacationing cow-orkers with sticky notes. The only camera I had handy to document the result was the one built into my cell phone, which does not quite have the kind of optics that accommodate wide-angle shots. I figured I’d just moasic the results together. Then, I remembered that I was taking all of the shots from different spots, but I seemed to recall a “Perspective” tool in the GIMP that I could maybe use to correct for that, and map the cube onto a two-dimensional window using some kind of projection.
It all went horribly wrong, but the nightmarish distortion of perspective was somehow compelling in a Bosch-via-surrealism way.
I also used a freely-available packaged panorama stitcher, hugin, which gave less jarring (thanks to better color blending) but no less disorienting a result:

Hi Colin,
Thought you’d want to give this tool a try: Auto stitch @ http://www.cs.ubc.ca/~mbrown/autostitch/autostitch.html
As an example, I’ve applied it to my panorama shots in my apartment here:

Colin:
I did find Autostitch when I was looking for a free panorama stitcher, but wound up using Hugin primarily because of its superior licensing situation, being free as in speech where Autostitch is merely free as in beer, and secondly because I figured an automatic stitcher would die of parallax poisoning on this image set, and that if it didn’t, the diff-geo calculations would melt my Ur-old laptop!
I see that it handled at least one nightmare-perspective image on your flickr stream, and pretty well. Did it do that fully automatically, and about how computationally hefty was it?
