Face Morphing

Overview

In this project, I morph faces together

Defining Correspondences

To more a face into another face, we first need to crop the pictures to be the same size, define correspondence points and triangulate.

Computing the "Mid-way Face"

With the points we can then compute the "mid-way face" by using a warp_frac of 0.5 and a dissolve_frac of 0.5.

Morph Sequence

From there we can make the entire morph sequence by gradually changing the warp_frac and dissolve_frac from 0 to 1.

The "Mean face" of a population

From here, I got a bunch of peoples faces, morphed each of the them into the average shape and then combined them to form the "mean face".

Caricatures

If we extrapolate from the mean (setting warp_frac to be greater than 1 or less than 0) we can form Caricatures

warp_frac=1.5
warp_frac=2.0
