David Crandall: Studying the World by Mining Photo-Sharing Websites
Abstract: The dramatic growth of photo-sharing websites has created immense collections of online images, with Flickr and Facebook alone now hosting over 50 billion images. While users of sites like Flickr are primarily motivated by a desire to share photos with family and friends, collectively (and perhaps unwittingly) they are generating vast repositories of online information about the world. Each of their photos is a visual observation of what a small part of the world looked like at a particular point in time and space. In aggregate, these billions of photos in combination with the non-visual metadata available on photo sharing sites (such as photo timestamps, geo-tags, and captions) present a rich source of information about the state of the world and how it is changing over time. In this talk I'll discuss some of our recent work in data mining and computer vision that aims to unlock this latent information from photo-sharing sites.
