Yahoo has just given Flickr its biggest makeover to date. Users of the photo-sharing behemoth now get a terabyte of free storage space, and the whole site has been given an updated image-centric look and feel. Other changes include the ability to upload larger images or videos, and new account options.
Researchers have devised a technique that allows a computer to create three-dimensional images of famous landmarks, by combining numerous two
-dimensional photos of those landmarks from Internet photo sharing sites such as Flickr. For the Building Rome on a Cloudless Day
project, 3 million photos of Rome were accessed online, and used to produce 3D images of all the city’s major landmarks. Utilizing commodity graphics hardware, it took a single PC less than one day to accomplish the task.
A rebuilding exercise is underway in Rome, but it’s not one that uses bricks and mortar, rather, it uses digital images – maybe even ones you provided unwittingly. A team from the University of Washington (UW) has developed a new computer algorithm that uses hundreds of thousands of tourist photos to automatically reconstruct an entire city in about a day. It’s thought that one use for the technology could be to provide visitors with an on-line virtual-reality 3-D tour of cities they visit.
