A morphing-based analysis of the perceptual distance metric of human faces
Nadine Gummersbach, Volker Blanz · 2010
This paper presents a psychophysical analysis of the discrimination thresholds of human faces that are varied along different directions in Face Space. Generated by a 3D Morphable Model, the stimuli are frontal views of original laser scans that are modified in shape, texture or both. Discrimination thresholds are then measured in a four Alternative Forced Choice (4AFC) design and a staircase method.
