METHOD AND APPARATUS FOR DETECTING FAKE FINGERPRINT, AND METHOD AND APPARATUS FOR RECOGNIZING FINGERPRINT |
| 摘要 |
An apparatus and method for detecting a fake fingerprint is disclosed. The apparatus may divide an input fingerprint image into blocks, determine an image quality assessment (IQA) value associated with each block, determine a confidence value based on the IQA values using a confidence determination model, and determine whether an input fingerprint in the input fingerprint image is a fake fingerprint based on the determined confidence value. |

1. A method of detecting a fake fingerprint, comprising:
dividing an input fingerprint image into blocks; determining an image quality assessment (IQA) value associated with each block; determining a first confidence value based on the IQA values using a first confidence determination model; and determining whether an input fingerprint in the input fingerprint image is a fake fingerprint based on the first confidence value, the fake fingerprint being a fabricated fingerprint. |
