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.
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。
According to the mechanism on forming of phase hologram in photorefractive crystal, by incoherently addition of the complementary hologram and the original hologram, the selective erasure and rewriting were accomplished.
