Abstrakt

Opisano szczegółowo algorytm detekcji oraz identyfikacji człowieka na podstawie punktów nodalnych twarzy. Zdefiniowano pojęcia: biometria, proces pomiaru biometrycznego, metody biometrycznej identyfikacji oraz kontrola dostępu. Przedstawiono opis opracowanego systemu biometrycznej identyfikacji wykorzystującego sztuczne sieci neuronowe. Podano wyniki badań oraz przeprowadzono ich wnikliwą dyskusję.Biometrics is the study of automated methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits. In information technology, a biometric authentication refers to technologies that measure and analyzes human physical and behavioral characteristics for authentication purposes. One of the most impressive examples of methods based on physical characteristics is facial recognition, which is the subject of this article. Biometric access control based on facial recognition system compare with other methods is not invasive, effective and easy in use that is why it was chosen. Human face is like a map with a lot of landmarks. Those special points make people exceptional. There are few main parts of the map which the program should identify: distance between eyes, width of nose, depth of eye sockets, cheekbones, mouth line and chin. After those measurements a person can be identified. The whole process of identification consists of five main steps: detection, alignment, normalization, representation and matching. The program was tested. Given results were satisfied. Non-braking development of IT section using biometrics will lead to the revolution of access control. In a few years people will not need a key, because they will already have one - the body.Biometrics is the study of automated methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits.
