An Approach to Brain Thinker Type Recognition Based on Facial Asymmetry

In the paper, a hypothesis of determining brain hemisphere dominance from a frontal face image is investigated. Behind this hypothesis, a face is considered as somatic/psychological background. A biometrical method based on person facial asymmetry characteristics is used. The method includes finding a proper vertical face axis and applying new asymmetry measures. Experimental observations confirm that there exists a correlation between the left/right brain hemispheres mutual functioning and a human face asymmetry. Moreover, examples show that the indication of the facial asymmetry is consistent with information about the hemisphere dominance. The presented method has been tested on color images of individuals with previously examined brain types.
