The paper offers a new algorithm to find coefficients which determines importance degree of the values of geometrical characteristics used to identify a human face on the basis of photo portraits. Significance of coefficients determining importance degree of the values of geometrical characteristics for identification is explained. Determination of coefficients determining importance degree of the values of geometrical characteristics for identification leads to the reduction in the number of values of insignificant geometrical characteristics, as well as to the improvement of identification quality and to the decrease in time spent for identification.

In this paper, algorithms of automatic identification of persons on the basis of their photographs are considered. For identification of persons, the comparative analysis of control systems by bases of images created in the different periods is carried out and their applied possibilities are shown.
