Face Morphing

CS 194-26 Project 3 by Muhab Abdelgadir

• Introduction

Face morphing is a fun tool for random purposes. The idea is to draw points that highlight our features to morph 2 faces together.

• Set Up

First, we must define corresponding points on two images, and after I defined these points covering the majority of my face, a Delaunay triangulation was computed on the average shape of these two point sets:

Mid-Way Face

To compute the midway face, we must compute the average location of each corresponding keypoint in the two faces, then warp both faces, and then dissolve the faces.

We must utilize affine transforms between triangles in the triangulation of key points on a face. Then we use the nearest neighbor interpolation for results.

Here is an example of my face with President Obama:

ME

PRESIDENT OBAMA

PRESIDENT ME

Mid-Way Face

To create the morph sequence, the parameter that controls contribution of keypoints was varied and computed the average face, which resulted in the following video: Go to Morph Video

Mean Face of a Population

I computed the average face of a Danish community. By taking all images of scientists staring straight ahead, taking average keypoints, we are able to compute average shapes:

Caricatures

I computed Caricatures of myself through the mean face. After taking differnce in shapes from the Danish population, we then exaggerate the difference with 𝛼 values, and by focusing the points specifically around my nose and eyes, there are no jagged edges and the details are very exaggerated:

𝛼 = 1 (almost no change)

𝛼 = 1.5

𝛼 = 2

𝛼 = 2.5

With a negative 𝛼 value, it is apparent that the area around my nose was extremely exaggerated due to the number of points centered there.

𝛼 = -1 (Hilarious)

Bells and Whistles: Themed Morphing Video

I created a morphing video that begins wit me in Highschool and progresses until the current day. From freshman year high school, to senior year college.
