Using techniques from the field of computer vision, Photosynth examines images for similarities to each other and uses that information to estimate the shape of the subject and the vantage point each photo was taken from. With this information, we recreate the space and use it as a canvas to display and navigate through the photos. Photosynth was inspired by the breakthrough research on Photo Tourism from the University of Washington and Microsoft Research. This work pioneered the use of photogrammetry to power a cinematic and immersive experience
Providing that experience requires viewing a LOT of data though—much more than you generally get at any one time by surfing someone’s photo album on the web. That’s where our Seadragon™ technology comes in: delivering just the pixels you need, exactly when you need them. It allows you to browse through dozens of 5, 10, or 100(!) megapixel photos effortlessly, without fiddling with a bunch of thumbnails and waiting around for everything to load.
More information on the history of Photosynth is available here.
I have experimented with Photosynth this past weekend. You can see the result by going to the Photosynth web site and typing SNAPDRAGONS in the search box. When the results appear click on the Synth titled Snapdragons and enjoy the results of my experiment and my snapdragons.
