In order to assess the perceptual salience of features
of Chernoff faces, a study was conducted in which
subjects had to rate the similarity of pairs of Chernoff
faces. It was found that the facial features differ considerably
in perceptual salience. Highly salient features
are the curvature of the mouth, the half-face
height, the half-length of the eyes, and the length of
the eyebrows, whereas the eccentricity of the lower ellipse
of the face, the position of the center of the
mouth, the separation and the slant of the eyes, and
the height of the brows have little influence on the
perception of Chemoff faces.
