US 8,712,190 B2 · Collating device, collating method, and program

Abstract

Provided are a collating device, a processing method and a collation program, in which a reference line is extracted from an image and each partial image is moved in a manner that the reference line becomes a predetermined one thereby to correct the image, and in which the corrected image is collated so that an authentication result can be obtained for a short time period without any rotating operation. At first, a reference line extracting unit extracts the center line or the contour line of the image as the reference line. Next, an image correcting unit moves each partial image in parallel thereby to correct the image so that the reference line obtained by the reference line extracting unit becomes a predetermined one. Moreover, an image collating unit collates the image corrected by the image correcting unit and a predetermined image to acquire an authentication result.

Dependent claims

A collating device for collating an image, wherein the image is at least one of the image of a finger and the image of a palm;

comprising:
a reference line extracting unit for extracting a predetermined reference line in the image;
an image correcting unit for correcting the image by moving each partial image so that the reference line acquired by said reference line extracting unit becomes a pre-decided one;
and
an image collating unit for collating the image corrected by said image correcting unit with a predetermined image,
wherein said image correcting unit is a device for correcting the image by translating in parallel each partial image so that the reference line acquired by said reference line extracting unit becomes a pre-decided one.

3 more elements

A non-transitory computer-readable medium encoded with a program for causing a collating device to execute:

a reference line extracting process of extracting a predetermined reference line in an image;
an image correcting process of correcting the image by moving each partial image so that the reference line acquired by said reference line extracting process becomes a pre-decided one;
and
a collating process of collating the image corrected by said image correcting process with a predetermined image,
wherein said image correcting process is a process of correcting the image by translating in parallel each partial image so that the reference line acquired by said reference line extracting process becomes a pre-decided one;
wherein the image is at least one of the image of a finger and the image of a palm.
