“Photosynth was born from … the marriage of Seadragon and Photo Tourism, a Microsoft project intended to revolutionize the way photo sets are packaged and displayed. Photo Tourism had begun as the doctoral thesis of a zealous 26-year-old University of Washington graduate student named Noah Snavely. One of Snavely’s advisors was Rick Szeliski, a computer-vision researcher at Microsoft Research, the company’s R&D arm … Working with Szeliski and a University of Washington professor named Steve Seitz, Snavely was intent on coding a way forward through a computationally forbidding challenge: how to get photos to merge, on the basis of their similarities, into a physical 3-D model that human eyes could recognize as part of an authentic, real-world landscape.”
