Astronomy photos on Flickr are automatically being analyzed and labelled with constellations, planets, and other objects. The group doing the IDing then has a big corpus of astronomical images, which has got to be valuable. Man, that is so cool. The physical coordinates and the timestamp go a long way towards providing the basic data necessary to do the math on this, but some clever image recognition and computation has to be necessary to pick out individual objects and label them. I’ve only posted a few astrophotos that I’ve taken, but I intend to post a lot more now. (Via Slashdot)
