Image2Geographic-Coordinate: A new Location Referencing System

5

This reminds me of  one of my Reference System’s classes in the Institute for Geoinformatics Muenster, Germany, when the professor asked to mention different ways to reference a location. And guys were mentioning: lat-long, place name, IP address, Wifi triangulation, RFID triangulation, Bluetooth  and so on.

Wao!, If I knew, I could have stunned the class with this new referencing system called IM2GPS.

This is really a cool development; some smart researchers have come up with an algorithm to estimate the geographic coordinates of a photo/image using purely data-driven scene matching approach.

According to the research, we have over 6 million geo-tagged photos on the internet (for example on flickr), by running a computer image matching process on a photo over the 6 million geo-tagged photos on the net, the likelihood of getting a similar photo already geo-tagged on the internet is high. Hence the geographic coordinate of the photo in question can easily be abstracted from the geo-tagged match.

They also noted that the  ”geolocation estimates can provide the basis for numerous other image understanding tasks such as population density estimation, land cover estimation or urban/rural classification” and that sounds interesting.

Interested in getting the details of the research get this Paper and enjoy!  For more info, enjoy the GoogleTechTalk video below..

  1. Hey there! Someone in my Myspace group shared this site with us so I came to check it out. I’m definitely enjoying the information. I’m book-marking and will be tweeting this to my followers! Wonderful blog and outstanding design.

  2. Hi, Neat post. There’s an issue with your site in web explorer, could test this¡K IE still is the marketplace leader and a good part of other people will pass over your great writing because of this problem.
