Face Morphing
Table of Contents
1 Introduction
I first learned about face morphing when I use Tik-tok. Users are able to morph their faces into a lot of interesting things, such as unicorns, celebrities, etc. A morph is a simultaneous warp of the image shape and a cross-dissolve of the image colors.
In this project, I computed the mid-way face, produced several morph sequences, and applied the algorithm to create some interesting images and videos.
2 Computing the Mid-way Face
In this part, I create a mid-way face of myself and George Clooney.

3 The Morph Sequence
In order to create a morph sequence, I need to set a number α as interpolation handler, then wee can simply weight out the triangle averaging and the color blending.
4 Population Mean Face
In this part, I used the dataset from Danes to compute a population’s mean face. To do that, we calculate the average triangles and adjust every picture to it, finalizing by blending all the colors together.
Now, I morph my face with the population mean face as well as the mean face to mine:
(up: my face to pop mean, below: pop mean to my face)

By extrapolating the morphing algorithm, I get this result:

6.1 Changing genders
I changed my friend into a man. The results follow.
Left: My friend, Right: pop mean
The faces don't perfectly match since I only chose four points. It can be further improved by selecting more corrospondance points.
6.2 My Growth
I morphed my face when I was about 4 years old when my face now. In my program, I set α₂ to be 0.5 which is arbitrary. The result follows:

My friends and I created a The result is available here.
