Google Face Search

Did you know that Google now offers a face search? If you go to Google Image Search and select advanced search, you should notice an option for "any content", "news content" or "faces". News content returns only images related to news articles. However, the "faces" choice is what I'm interested in here.

It is best demonstrated by example. Compare this normal image search and this face search. You'll notice that while there are a few faces in the normal search, there are also many other images, whereas the face search only contains faces. I flicked through several pages and have yet to find a false positive. It falls on the safe side with lots of faces discarded, however I agree with this strategy for early adoption. It is not good at finding small faces, especially if there are many in the picture.

The earliest post I could trace back to was this one.
