Navigating the World's Photographs
Google Tech Talks
June 13, 2007
There's a big difference between looking at a photograph of a place and being there. But what if you had access to every photo ever captured of that place and could conjure up any view at will? With billions of photographs currently available online, the Internet is beginning to resemble such a database, capturing most of the world's significant sites from a huge number of vantage points and viewing conditions. For example, a Google image search for "notre dame" or "grand canyon" each returns more than half a million photos, showing the sites from myriad viewpoints, different times of day and night, and changes in season, weather and decade.
This talk explores ways of transforming this massive, unorganized photo collection into visualizations of the world's sites, cities, and landscapes. After a brief recap of our work on Photo Tourism and Photosynth, I will focus on current efforts and newest results, in the domains of 3D scene reconstruction and new visual interfaces for navigating photo collections.
