What is an Average Face?

An average face here implies a synthesized image generated by mixing several portraits. Its facial features such as the distance between the eyes, the shape of facial contour, and skin color are averages of the mixed faces.

Psychology of Facial Attractiveness

"Average faces have attractive looks." Is that true?

Some psychologists have hypothesized that averageness is one of important factors of facial attractiveness.
You can investigate the validity of the averageness hypothesis of facial attractiveness using this App.

Pupils Only Mode and Eye Contours Mode

In order to make a beautiful average face, positions of markers should be adjusted carefully.

At the beginning of a workflow, place one marker for each eye in the Pupils Only mode.

Then, switch to the Eye Contours mode or PRO mode. However, if you would like to make an average face casually, you can register the face in the pupils only mode.

In the above example, the right eye of the average face looks fine, but the left eye is blurred.

This is because only one marker is used for each eye.

In order to capture the contours of the eyes, you need to switch to the Eye Contour mode (or PRO mode).

Start a workflow in the Pupils Only mode. After placing one marker for each eye, tap the 'Eye Contours' button. Then, four additional markers appear around the marker placed at the pupil of each eye.

Place these markers along each eye contour.

In the Eye Contour mode, the eye contours were rendered more clearly.

In the PRO mode, more markers are usable.

It should be noted that faces registered in the Pupils Only mode and those registered in the Eye Contours mode should not be mixed.

Otherwise, curious faces are generated.

Eyebrows: How to use PRO mode

Blurred eyebrows

The facial structure employed in this App does not have eyebrows. Thus, the average face would in general have blurred eyebrows.

One workaround is to place markers for eye contours on eyebrows.

Normal usage

In the Eye contours mode, four additional markers appear around each eye. They are denoted as A~D and a~d in the figure. Since the markers are placed around the eyes, the eyebrows are not captured.

Capturing the eyebrows

By placing the markers in the manner as shown in the figure, the shapes of the eyebrows can be captured.

PRO mode

In the Pro mode, additional markers E and e appear.

You can use these markers to capture the arc of each eyebrow.


Underlying Facial Structure

The triangular patches shown here represent the facial structure employed in this App. You can see this triangular patches while editing the markers in the PRO mode.

Each marker corresponds to a vertex of a triangular patch.

You can freely adjust the position of each marker. However, in order to obtain a beautiful averaging result, each marker should not traverse the sides of the other triangular patches.

Good Configuration

In this example, no marker (i.e., no vertex of a triangular patch) traverses the sides of any triangular patches. Thus, this is a good configuration.

Bad Configuration

In this example, however, two markers commit violations; they traverse sides of other triangular patches. In this case, strange edges or contours would appear in the averaging result.

If you find unexpected edges in an averaging result, check out the occurrence of the violation noted above. You can view the triangular patches in the PRO mode.

Creation of non-existent faces by averaging

Creating average faces is amazingly easy. You can create beautiful, cool, bizarre, or funny portraits even if you have no artistic skill (like me).
