Not all faces are alike

The face is the most important vehicle of human communication because of the fact that faces are not alike. The major objective of this article is to demonstrate qualitatively and quantitatively this determination based on 108 images. The first approach is based on Figure 1, which demonstrates the following five shapes of the human face: round, square, heart shaped, oval, and long. The disadvantage of this approach is that it is based on the eye of the beholder. In other words, 2 people might decide differently for the same face shape. The second approach is a quantitative one based on the determination of face symmetry. The major conclusion in both cases is that faces are not alike.
