Abstract

A personal authentication apparatus includes a facial region extraction which extracts an image of a facial region of a person obtained from image sensing input unit, a guide unit which guides motion of the person of interest, a feature amount extraction unit which extracts the feature amount of a face from the image of the facial region extracted by the facial region extraction unit while the motion is guided by the guide unit, a dictionary registration unit which registers the feature amount extracted by the feature amount extraction unit as a feature amount of the person of interest, and an authentication unit which authenticates the person of interest in accordance with the similarity between the feature amount extracted by the feature amount extraction unit, and a feature amount which is registered by the dictionary registration unit.

Dependent claims

A personal authentication system comprising:

a facial region extraction unit configured to extract images of a facial region of a person obtained from an image sensing input unit;
a guide unit configured to guide motion of the person of interest;
a feature amount extraction unit configured to extract a first feature amount of a face from a first image set of the facial region extracted by the facial region extraction unit;
a dictionary registration unit configured to register the first feature amount extracted by the feature amount extraction unit from the first image set extracted while the motion is guided by the guide unit as a feature amount of the person of interest;
and
an authenticating unit configured to perform authentication using a second feature amount extracted at authentication from a second image extracted by the facial region extraction unit without guided motion and comparing said another second feature amount with the first feature amount extracted from the first image set extracted during guided motion and stored in the dictionary registration unit.
