Abstract To overcome the influence of the image quality on the single modal recognition system, a fingerprint and finger vein dual-mode recognition method based on image quality evaluation is proposed. The image quality scores of the fingerprint are obtained by the proposed method. And according to its characteristics, the finger vein image quality assessment is designed for the first time to overcome the influence of image quality on identification results. Two classifiers are then designed for fingerprint and finger vein recognition respectively. The final recognition is achieved by the fusion of two quality scores and the recognition results of the classifiers at the decision level. The proposed method overcomes the limitations of image quality on single-modal biometrics, and effectively improves the recognition performance of the system. Thus, the validity of the method for multimodal biometric identification is demonstrated.
