Microsoft's Photosynth Makes Photos a 3D Experience

The really impressive thing about Photosynth is how far it has come in the last year. It used to take hours to weeks to create synths from hundreds of pictures. The processing time is dominated by

1. Keypoint detection (SIFT or a similar algorithm)

2. Keypoint matching for each pair of images with approximate nearest neighbor (ANN) search on kd-trees

3. Structure from motion to recover rotation and the relative location of photos

Yes, it only runs on 90% of desktops.

What a weird response. I meant it as a disappointment that I couldn't see it in action being on OSX.

I did notice that as well. But I got a Windows only message when trying to give it a whirl.

I think he means that it's a (Windows) plugin for your browser. Both the picture uploader and the viewer are Windows-only for now.
