Comment 129 for bug 507511

I had a look around the internet for something suitable, first of all apparently IPhoto 9, I think, has this face recognition technology. But I guess Apple just bought the company that developed it originally, because I just can't find anything about it on the internet.

With regards to open source equivalents, there is libFace, http://libface.sourceforge.net/index.html, but that is in preAlpha and doesn't look it has been active for a while. Other then that, might have to write own code for it. One of the ideas is Eigen Face.
