Abstract  In the typical fingerprint indexing method based on minutia cylinder-code(MCC) feature, the minutiae local structure is adequately taken into account. Since the global structure of fingerprint is ignored, the accuracy of fingerprint retrieval is limited. Therefore, deep convolutional neural network is employed to learn the global feature(deep convolutional feature) of fingerprint. Then, the MCC and deep convolutional feature are fused to improve the fingerprint indexing accuracy. Experiments are carried out to compare the proposed method with other prominent approaches on three benchmark databases. Besides, the property of deep convolutional feature is analyzed. Experimental results show that the proposed method effectively improves the accuracy of fingerprint indexing.
