Photosynth

13 December 2007

The best talk I saw at the Web 2.0 conference in Berlin this year was from Blaise Aguera y Arcas, Software Architect at Microsoft Live Labs. He showcased the latest updates of Photosynth, a new technology from Microsoft Labs that stitches photos together from any number of sources to create (the illusion) of a 3-D model of a building or landmark. If you’ve not seen this yet, do so. Here’s a brief video of Blaise showcasing Photosynth at the TED conference.

Basically, the software recognizes unique points on photos of a stationary geo-location and is able to align them with other photos. If you get enough photos in a collection, you effectively have a 3-D version of the original location. Take Notre Dame in Paris: you can point Photosynth at a collection of photos on Flickr, forn instance, and Photosynth compilies a 3-D rendering of the building. Sure, there are some ugly seams, but it’s a pretty amazing results nonetheless. With the ubiquity of digital cameras these days, we could potentially have every place on earth represented in 3-D on the web in the future.

The interesting thing would be to apply this principle to tagging. If you have a rich, complex folksonomy, would you be able to pick out unique descriptive points, and then be able to “sew” the terms together to get a clearer semantic picture of the objects being described? I suppose that’s  what things like Twine are trying to do, in a sense.

Map Mixer from Yahoo!

15 September 2007

Yahoo! has a new service called Map Mixer. You can upload an image of a map of just about anything and overlay this onto a Yahoo! map. There is then an opacity control to show more or less of the uploaded map. This ultimately allows people to tie their local areas and local mapping needs into a broader context.

For example, see the map of University of Southern California. This has far more detail of the campus than a normal Yahoo! map would ever show, but now you can also see how to get to the campus and where it’s located geographically.

You can also show a satellite image for the background map. This is particularly interesting, and it could be great for hiking maps and such. Very simple idea, but also very cool.
