Byron's Blog: Unlabeled Object Recognition in Google+

Google+ released an amazing feature that uses object recognition to tag photos. Here is a Reddit thread discussing it.

This train came up for [car]:

This goat came up for [dog]:

These fireworks came up for [flower]:

This millipede came up for [snake]:
