METHOD AND DEVICE FOR FACIAL IDENTIFICATION OF A PERSON

摘要

The invention relates to automatic facial identification of a person. The invention makes it possible to accelerate the identification process and to improve the certainty of identification. The inventive method for facial identification of a person consists in selecting fragments containing eye images, by pre-selecting the primary feature points corresponding to the position of the eyes and by determining the location of the points for each eye, and in comparing said images with the predetermined references of the right and left eyes. Said method also consists in separating informationally significant areas on the separated fragment of an information field by using the Gaussian ellipse function, in building the facial references of persons to be identified by using at least two types of orthogonal basis functions, for preliminary search and identification, and for detailed identification and building additional references used for final identification. The identification is carried out according to the integral estimation of a resemblance degree for each analysed fragment by means of a two-step process consisting in comparing the references for preliminary search and identification and comparing the references for detailed and final identification.
