Mixing Faces

Hiren created a system to "make faces" for his university project, supervised by Peter McOwan. We can think of colour as made up of adding 'colour elements' (wavelengths). Similarly can we find the set of images to add together to make faces. Shown are these 'face elements', and in the red box a set of new faces made by mixing together the 'face elements'.

Interesting fact: the face element at the top left is the "average" face from the large set of different faces used to build the system, to most people it looks particularly attractive, so do people prefer average faces?

Hiren became a University systems programmer
