摘要: Quality estimation of fingerprint image can be used to control quality at the enrollment stage automatic recognition system and guide enhancement image. This paper proposes a neural network based method. It estimates correctness ridge orientation each local block using then computes global on correctness. The proposed method is improves accuracy system.
