I think there were 20 girls.
And then you “morph all the face images into a mean face shape, then average over the picture values… Here is the result.”
And then we see here “the coefficients of the 20 contestants. Note that most of the energies are concentrated on first two eigenvalues.”
Thus, we “plot the coefficients corresponding to the first two eigenvectors. We can now see how similar the appearance of these contestants are.”
Really, find the very interesting original post here, which has much more info and diagrams, but I just wanted to share with you my interesting findings on the web.
While the poll results are out and is available on the official website, I would probably not be able to identify each one correctly if I were to be tested…
