Biometrics of Asymmetrical Face

Abstract

Traditionally, in face authentication/identification methods the presumption concerning face/head symmetry is used. For novel applications that concern creating techniques by means of which it is possible to reproduce the extraordinary complexity of skin, muscle, eye and hair movements conveying emotion, gesture, psychological state or psycho-sociological traits, we begin to create new research direction called Biometrics of Asymmetrical Face. In this paper, a novel type of 2D precise normalized model of a face – called Czestochowa-face model – for modern and prospect authentication/identification techniques creation is presented. Also, the results of creating and pioneer researching the ophthalmogeometrical technique and the facial asymmetry technique, which are based on the Czestochowa-facemodel, are given. Some attention has been drawn to interdisciplinary research context. Beside the first-hand usage, the novel type of face model and the techniques may be employed in the areas of human-computer interaction, identification of cognition-psyche type of personality for personnel management, and some other future applications.
