Abstract
An image processing device outputs, by using a result of machine learning, an image including three or more gradations and indicating a central line in response to an input of a fingerprint image, the machine learning being performed by using data including at least a fingerprint image, central line information indicating a central line in the fingerprint image, and zone information indicating a zone that is a portion of the fingerprint image which is effective for fingerprint collation, and generates a binary central line image based on the output image.
Claims7
An image processing device comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- output, by using a result of machine learning, an image including three or more gradations and indicating a central line in response to an input of a fingerprint image, the machine learning being performed by using data including at least a fingerprint image, central line information indicating a central line in the fingerprint image, and zone information indicating a zone that is a portion of the fingerprint image which is effective for fingerprint collation;
- and
- generate a binary central line image based on output image.
An image processing method comprising:
- outputting, by using a result of machine learning, an image including three or more gradations and indicating a central line in response to an input of a fingerprint image, the machine learning being performed by using data including at least a fingerprint image, central line information indicating a central line in the fingerprint image, and zone information indicating a zone that is a portion of the fingerprint image which is effective for fingerprint collation;
- and
- generating a binary central line image based on the output image.
A non-transitory computer-readable recording medium storing a program which causes a computer to execute:
- obtaining an image by applying, to a collation target fingerprint image, processing of outputting, by using a result of machine learning, an image including three or more gradations and indicating a central line in response to an input of a fingerprint image, the machine learning being performed by using data including at least a fingerprint image, central line information indicating a central line in the fingerprint image, and zone information indicating a zone that is a portion of the fingerprint image which is effective for fingerprint collation;
- and
- generating a binary central line image based on the obtained image.
