Teaching an Alien to Recognize Human Faces

[Four]

Hello everyone :)

There is an alien that just came to Earth and is having trouble recognizing peoples faces. We also have trouble recognizing his face; where his eye is on one hand and a mouth on the other. Luckily for us the alien understands our language and simple colours.

The task is to teach the alien how to recognize human faces. Post a process/description using pictures and any learning material for an alien might do to recognize human faces; the second person gives an example where the process/description is flawed and inputs his new description adding/subtracting and etc.

The winner is the person who posts a process/description that no one can find a flaw :).

example:
user 1;
Human faces have 2 eyes
user 2:
some humans lost an eye

Lets start:

1: find something that is generally one color
2: Check that its resonably symetric
3: check that there is atleast one eye
