Face Detection Neural Network Training Data (databases, number of faces etc)

Question

I'm creating a face detection program using neural networks, and looking for some reliable training sets. I'm aware there's various sets around the web, but I've not idea how good they are. Any ideas where to start?

Answer 1

A certainly entertaining way would be to get faces from google image search.

Answer 2

CMU has some nice face datasets, especially if you're trying to detect the location of the face, and not only whether its present or not.

Essex university facial images collection is another commonly used dataset.
