Yes, In fact we've been working on this for a while ago & there were some troubles in university (a PhD said we are losers & that's old project done before we just inventing the wheel) sadly we didn't complete with it.

Anyway, as we've done, this technique gets patterns of face and every part of the face like eyes, nose, mouth, cheeks..etc. collecting everything as one big pattern, it should be unique for every person, we tried Several Fourier transforms & Wavelets methods to achieve it, but we didn't get to the point to make it work practically but theortically I think it would work with search for person by image very well.
