In modern biometric applications as well as in applications from the range of advanced artificial intelligence and psychology, quantitative "measuring" of information with the traits of facial asymmetry and its proper interpretation was initiated; the aims may be authentication/identification of a user and/or defining cognitive-mental personnel types in terms of psychological-social context. In the work, the result of novel supposition and experiment in direction of algorithmization of indispensable procedures of the above mentioned approach provides: 1) finding the "truthful" vertical facial axis projection on the base of it's frontal image, 2) creation and experimental verification of new (linear and area) integral measures of geometrical asymmetry of comparable faces. A forming procedure of elaborated technique is so-called the MwW-normalization of a frontal facial image in absolute length/area units called Muld/Muld². Muld[pixel] equals 10 ± 0.56 mm (that is external diameter of eye iris of any person, which has reached 4 years old). Muld² [pixel] equals the proper area of eye iris on a person's image. The work contains also interesting knowledge concerning the context of elaborated technique.
