Sure is - you just need to come up with an algorithm that takes two images and calculates that percentage.

There is no generally agreed-upon definition of what constitutes image similarity; what is your definition?

Ooh boy, you've certainly found an extremely advanced topic to work on. Facial recognition is definitely not trivial. For instance, if the eyes are slightly closed the pixels of the images are quite different, yet you still want the two images to match.
