Every person has some aggression or aggressivity level and low aggression level is the same pathology as high aggression level [1]. Maybe it is more correct to call low aggressive level - the activity level, it sounds less dangerous. The level of aggression is one of the base human emotions and now, every Vibraimage system user could control his own aggression level, or aggression of friends, partners and any controlled person. The aggression level calculates [2] by the following equation:
where Ag – calculated aggression level of object for time period of N frames; Fm – maximum frequency of vibrations for N frames; Fi – maximum frequency for “i” line for N frames; F – average value of maximum frequency in lines for N frames; n – lines number with frame difference more than threshold for N frames.Aggression equation algorithm includes different filters, settings and adjusting described in vibraimage software system Manual. According to the suggested equation aggression level directly depends on two main components - frequency mathematical expectation (mean) and standard deviation (sigma). This equation based on Konrad Lorenz theoretical and practical researches and Elsys experience, patents and know how.External vibraimage (aura) of persons with high aggression level display below:

Normal person aggression (activity) level calculated by the vibraimage system with default micro settings has range (20-65)%. Person with more high or low aggression (activity) level differs from statistical norms and could be stopped in airport for more detail personal control.
