代码说明:

  基于dct的伪随机序列的数字图像水印,算法较为简单,鲁棒性一般,不能很好地抵御噪声攻击(Dct pseudo-random sequence-based digital image watermarking algorithm is relatively simple and general robustness against noise attack can not)

    利用夹角余弦距离进行样本数据分类。实现步骤主要分为以下两部分:a、待测样品X与训练集里每个样品Xi的距离采用夹角余弦距离公式计算。b、循环计算待测样品和训练集中各已知样品之间的距离,找出距离待测样品最近的已知样品,该已知样品的类别就是待测样品的类别。(Using the sample data classification Angle cosine distance.Implementation steps are divided into the following two parts: a, sample under test with each of the samples in the training set X Xi distance using the included Angle cosine distance formula.B, loop calculation under test samples and the distance between the known samples training focus, find out the known closest to the sample under test samples, the samples of known category is the category of the sample under test.)

    基于加权LS-SVM的非线性系统内模控制的仿真程序,由于辨识信号采用的都是随机信号,不是数值固定的信号,所以程序每次运行的结果都可能有所不同(Emulator mode control based on weighted LS-SVM nonlinear systems identification signal are random signal, not the value of the fixed signal, so the program each time you run the results are likely to differ)
