The study's aim was to identify female and male face shape variability in order to establish typical profiles for the design of masks. A specific data acquisition photogrammetric station was used for this purpose. A preliminary survey using anthropometric techniques was conducted on 301 females and 208 males, randomly selected from the French military population, in order to constitute two samples of 30 males and 30 females for the stereometric survey. For each subject, the stereorestitution of face photos was made on three sets of data: (1) 37 anatomical landmarks previously identified by a black point marked on the face; (2) 7 anatomical arcs, also drawn with a black pencil; and (3) 1500#x2013;2000 points distributed on horizontal cross-sections at different vertical levels.
