Photosynth is an amazing new technology, created through a unique collaboration between Microsoft and the University of Washington. The application will change the way you think about digital photos by taking a large collection of photos of a place or object, analyzing them for similarities, and displaying them in a reconstructed 3-dimensional space. The groundbreaking innovation began with Photo Tourism research by UW graduate student, Noah Snavely, UW faculty member Steve Seitz, and Rick Szeliski, Microsoft Research. The new Microsoft Live Labs organization -- dedicated to advancing the state-of-the-art in Internet products and technology -- embraced the Photo Tourism technology and combined it with complementary photo browsing technology created by the team at Seadragon, a Madrona-backed Seattle startup headed by Blaise Aguera y Arcas that had been acquired by Live Labs.A Photo Tourism research presentation, and the rollout of the Photosynth prototype by Live Labs, stole the show at the 2006 SIGGRAPH conference.
