Photosynth is a collaboration between Microsoft and the University of Washington based on the groundbreaking research of Noah Snavely (UW), Steve Seitz (UW), and Richard Szeliski (Microsoft Research).
The Photosynth Technology is a taste of the newest and most exciting way to view photos on a computer, yet ,uptil now, a bit slow even for DSL users. The software takes a large collection of photos of a place or an object, analyzes them for similarities, and then displays the photos in a reconstructed three-dimensional space, showing you how each one relates to the next.
You can access gigabytes of photos in seconds, view a scene from nearly any angle, find similar photos with a single click, and zoom in to make the smallest detail as big as your monitor.
On the project presentation on TED talks*, You can see how Photosynth really collaborates the images contributed by of thousands of people enriching the value of each with the value added by networking all these images together...
