Two tests were performed during each experiment:
- Test 1 maximized extraction and matching accuracy. VeriFinger 13.1 algorithm reliability in this test is shown as blue curves on the ROC charts.
- Test 2 maximized extraction and matching speed. VeriFinger 13.1 algorithm reliability in this test is shown as red curves on the ROC charts.
Receiver operation characteristic (ROC) curves are usually used to demonstrate the recognition quality of an algorithm. ROC curves show the dependence of false rejection rate (FRR) on the false acceptance rate (FAR).
