I noticed the thread on Photosynth and thought I would add a little more about that research group. I know Rick Szeliski and Matt Uyttendaele, very smart people.
I've tried pretty much all of the panorama stitchers out there. Adobe's is by far the worst, and Microsoft's is by far the best. Szeliski's algorithms are currently found in Microsoft Image Suite 2006. Unlike most stitchers, it is based on a robust treatment of the general camera projective transformations, so it can handle rotations, panning, zooming and even limited camera-position changes (modulo big visiblity changes of course). [attachment=7042:attachment] Here's an example that first impressed me. In a Soviet documentary film I own, they discuss this diagram of the Venera soil-drilling apparatus, but they never show the whole diagram. They pan around and zoom in and out, and I didn't expect to be able to resolve all that into one image. I was quite surprised when Rick's program did it. An updated version of the stitcher is in a new product, Microsoft Graphic Designer, which will give users more control over a big class of transformations (affine, homography, 3D rotation, etc). It handles lens distortion and a variety of projection surfaces. I haven't tried it myself yet. link I have Panorama Factory and Autostitcher of course, but I never use them now, they are nowhere near as powerful as DIS2006. Uyttendaele also recommended a program to me called ptlens for some non-projective transformations like vignetting. |

...and some more bad news...
QUOTE She also is the lead imaging scientist on the New Horizons Pluto/Kui- per Belt mission,launched in early 2006,which will take the first look at Pluto and other bodies in the so-called Kuiper Belt past the planet Neptune. So guys no stitching of that Jupiter/Pluto/KBO/etc objects... Maybe that is the reason why we still haven't seen first Jupiter photos from NH... There ain't no NH Raw Images site??? . .. ...weeel we could buy a poster from Diamond Sky Productions for some $$$... -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.
