Using computer vision techniques, Photosynth examines images for similarities to reconstruct a 3D model of a space from multiple photos taken of that space. Seadragon technology enables smooth zooming into high-resolution photos without downloading them. Photosynth puts the user in the space like no other by capturing sweeping scale and allowing focus on fine details through synthesis of photos.

7. 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.

10. In 2006 Microsoft acquired small, Seattle-area startup Seadragon , whose technology is capable of delivering a buttery smooth experience browsing massive quantities of visual information over the Internet. It is all the detail you want, exactly when you want it, with predictable performance regardless of the amount of data—from megapixels to gigapixels. The same year, from the groundbreaking research of Noah Snavely (UW), Steve Seitz (UW), and Richard Szeliski (Microsoft Research), a prototype called ‘photo tourism’ was born. The idea was simple: given a few dozen or few hundred photos of a place, is there enough information to reconstruct a 3D model of that place? The advanced computer vision techniques pioneered in pursuit of this goal form the basis of the synther.

17. Whether it’s a quiet creek in the woods of Pennsylvania, or the grandeur of the interior of St Paul’s cathedral, Photosynth puts you there like nothing else can. It can capture the sweeping scale of a mile of the Grand Canal in Venice, and focus in on the exquisite rot at the waterline of a beautifully decaying palazzo doorway.

18. Want to share your amazing new room with your friends—after all what justice do a bunch of thumbnails do for a room that took you a month to decorate? Only a synth can capture every detail And it’s not just for spaces and places. Photosynth is an amazing way to share the full juicy details of the stuff in your life.
