提出一种提高综合滤波器鉴别率的有效方法，其做法是：对样本集在等相关峰条件下求解综合滤波器的同时，使样本集的互补样本满足零相关峰条件．此方法把训练模式类同所有其它模式类在映射空间的距离拉大，有效地提高了综合滤波器的鉴别率，以取自同一手指的多个指纹为样本集，求解综合鉴别函数后，建立了指纹的实时模式识别系统．实验结果表明本文提出的改进方法对提高综合滤波器的鉴别率是非常有效的．
An effective method to improve the discrimination rate of synthetic filter is proposed. The method is that the complementary sample of the sample set satisfies the zero-correlation peak condition while the synthetic filter is solved under the condition of equal correlation peak. This method enlarges the distance between the training pattern class and all other pattern classes in the mapping space and effectively improves the discrimination rate of the synthetic filter. Taking multiple fingerprints taken from the same finger as a sample set, the comprehensive discriminant function is established and then established Fingerprint real-time pattern recognition system. The experimental results show that the improved method proposed in this paper is very effective in improving the discrimination of the synthesis filter.
