We found changing image sharpness can improve palmprint recognition performance. Introduce EAV to assess palmprint image sharpness. We’ve found the optimal sharpness range [E1, E2] that can optimize the performance. Using image smoothing and restoration can tune the images to [E1, E2]. Our approach can reduce the EER of palmprint recognition by 15%.
