A biometrics device, a biometrics method, and a program

Japanese Patent JP6069582

B2

A biometrics authentication device 1 is configured to include: a filter 41 that extracts from an input image directional features that respectively correspond to directions different from each other; an perpendicular filter 42 that, from among the directional features extracted from the filter 41, decreases a luminance value of the entirety of a directional feature that corresponds to a prescribed direction, increases a luminance value of the entirety of a directional feature that corresponds to a direction perpendicular to the directional feature that corresponds to the prescribed direction, and outputs other directional features with no change; a non-directional feature generation processing unit 43 to 45 that generates a non-directional feature on the basis of the directional features output from the perpendicular filter 42; a matching processing unit 5 that obtains a similarity between the non-directional feature and a registered non-directional feature stored in a storing unit 7; and a determining unit 6 that determines identity by using the similarity.
