Reading that, I can't help but wonder how similar a machine-learned eigenface is to an infant-learned one. http://lawcomic.net/guide/?p=3273

I wonder if there is some way to simulate the effect of growing up among people of different races on eyewitness identification and test if it matches what this lawyer is saying at http://lawcomic.net/guide/?p=3282

As I understand it, eigenfaces require preprocessing to orient and align the images. That doesn't seem to have come up here. Maybe Amazon is really consistent about centering models in dress photos?
