摘要
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．
We propose a method to improve discrimination for synthetic discrimination function (SDF), which is carried out by training the complementary samples under the condition of zero correlation peaks while the samples under the condition of equal correlation pobs. Therefore, the distances between the trained class and all other classes are increased in the decision space and high discrimination is resulted from. On the other hand, the advantage of the distortion-invariant recognition for synthetic discrimination function is kept as well. Experimental results related to fingerprint identification are given.
