A Method of Evolving Finger Vein Template
Darun Tang, Beining Huang, Wenxin Li, Xiaoming Li · 2012
In a finger vein verification system, when running for a long time, the captured templates could be different from the registered ones because of the user habits changing, the devices ageing, and some other factors. The unsteady discrepancy between templates of the same finger affects the verification results seriously. Therefore, we design a templates evolution method to get evolving templates, which can reduce the influence of templates changing when matching. Experimental results show that using evolving templates can make the EER of the system reduced from 6.3% to 3.5%.
