WO2001075774A1 - Method for person identification - Google Patents

Abstract

The invention relates to the authorized access systems, more specifically to methods for person identification with the aid of a face pattern analysis. The inventive method is characterized by developing a standards set using an optical sensor during determined movements of a head of a person to be identified. Said standards are embodied in the form of discrete two-dimensional information fields containing an information about characteristic phases of the face turn of said person. A horizontal band comprising eyes being emphasized on a white and black face image with the aid of anthropometric data, the face phase of movement is estimated by analyzing the image asymmetry within a visible band. The estimated results are used as a key information for searching in a computer memory the face standards possessing the phases close to the estimated phase and said parts being compared with standard parts identified in the computer memory, a quantitative measure of a similarity thereof is defined.
