Abstract
A biometric information correcting apparatus includes: a palm print feature point extracting unit that extracts two feature points of a palm print of a user's hand from a first image obtained by capturing the palm print and representing the palm print; and a correcting unit that rotates a vein pattern of the user's hand on a second image or a feature portion of the vein pattern extracted from the second image, according to an orientation of a line joining the two feature points, the second image being obtained by a biometric information acquiring unit capturing the vein pattern, the second image being obtained by a biometric information acquiring unit capturing the vein pattern.
Claims20
A biometric information correcting apparatus comprising:
- a processor configured to extract two feature points of a palm print of a hand of a user from a first image obtained by capturing the palm print and representing the palm print;
- and
- rotate a vein pattern of the hand on a second image or a feature portion of the vein pattern extracted from the second image, according to an orientation of a line joining the two feature points, the second image being obtained by a biometric information acquiring device capturing the vein pattern.
A biometric information correcting method comprising:
- extracting, by a processor, two feature points of a palm print of a user's hand from a first image obtained by capturing the palm print and representing the palm print;
- and
- rotating, by the processor, a vein pattern of the hand on a second image or a feature portion of the vein pattern extracted from the second image, according to an orientation of a line joining the two feature points, the second image being obtained by capturing the vein pattern.
A non-transitory computer-readable recording medium having recorded thereon a computer program for correcting biometric information that causes a computer to execute a process comprising:
- extracting two feature points of a palm print of a user's hand from a first image obtained by capturing the palm print and representing the palm print;
- and
- rotating a vein pattern of the hand on a second image or a feature portion of the vein pattern obtained from the second image, according to an orientation of a line joining the two feature points, the second image being obtained by capturing the vein pattern.
A biometric information correcting apparatus comprising:
- a processor configured to extract two feature points of a palm print of a hand of a user from an image obtained by a biometric information acquiring unit capturing the hand and representing a vein pattern of the hand and the palm print;
- and
- rotate the vein pattern on the image or a feature portion of the vein pattern extracted from the image, according to an orientation of a line joining the two feature points.
