Abstract
An image processing apparatus includes a first skeleton extraction means, a second skeleton extraction means, and an integration unit. The first skeleton extraction means discriminates a valid region and an invalid region in a fingerprint image which is input, and extracts skeleton lines in the valid region. The second skeleton extraction means extracts skeleton lines in the invalid region. The integration unit generates a skeleton image by integrating the skeleton lines extracted in the valid region and the skeleton lines extracted in the invalid region.
Claims10
An image processing apparatus comprising:
- a memory storing instructions;
- and
- one or more processors configured to execute the instructions to:
- discriminate a valid region and an invalid region in a fingerprint image which is input, and extract skeleton lines in the valid region;
- extract skeleton lines in the invalid region;
- and
- integrate the skeleton lines extracted in the valid region and the skeleton lines extracted in the invalid region, and generate a skeleton image corresponding to the fingerprint image.
An image processing method, comprising:
- discriminating a valid region and an invalid region in a fingerprint image which is input, and extracting skeleton lines in the valid region;
- extracting skeleton lines in the invalid region;
- and
- integrating the skeleton lines extracted in the valid region and the skeleton lines extracted in the invalid region, and generate a skeleton image corresponding to the fingerprint image.
A non-transitory computer-readable recording medium storing a program, the program causing a computer to perform a process comprising:
- discriminating a valid region and an invalid region in a fingerprint image which is input, and extracting skeleton lines in the valid region;
- extracting skeleton lines in the invalid region;
- and
- integrating the skeleton lines extracted in the valid region and the skeleton lines extracted in the invalid region, and generate a skeleton image corresponding to the fingerprint image.
