Histogram of systematic eccentricity of the endocanthion of the eyes

Left: for the 3D database (Troje & Bülthoff, 1996), and Right: for the 2D analysis of frontal pictures of the face in a British population of mostly male subjects. Red curves: fitted normal distribution

Correlations between the asymmetries of some of the landmarks from the analysis of the 3D Database of Troje & Bülthoff (1996)

Each panel shows the correlation of two of the landmarks. The lowest (Nasion-Menton) and the highest (Exocanthion-Endocanthion) are the lowest and highest correlations respectively of all pairs of landmarks.

Matlab script for analysing the data base of adult faces

Matlab script for computing the Aurofacial Asymmetry as predicted by the Axial Twist hypothesis. The draft of this script was written by Niko Troje. The author (MdL) wrote most of the analysis. The script needs the symmetric face and the individual faces from the Faces database, and the Facerenderer functions that come with it. Access can be obtained by contacting http://faces.kyb.tuebingen.mpg.de
