牛顿环与指纹识别

Nerve-network and Dactyloscopy

利用牛顿环的干涉条纹和指纹对比的结果 ,提取各条指纹特征数据作为神经网络的样本输入 .经过Bp网络学习、训练后 ,系统便可打印出实际输出和期望输出的曲线 ,此曲线即为指纹曲线 .可作为指纹材料输入指纹库 。

The individual characteristic data of fingerprints were ertracted from results of comparison between Newton interference stripes and fingerpints, and were input as sample into nerve network. The real output and expected output curves, i.e., the fingerprint curves may be printed out by the system and be saved as fingerprint data in the data base for identification of individual's fingerprints.
