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.
