%基于DCT的水印算法
%数字水印处理系统主要由水印嵌入和水印检测两个过程。
%水印嵌入过程为:数字水印(X)、原图像(I)和密钥/公钥(K)通过数字水印嵌入算法形成嵌入水印后的图像(I*)。
%水印检测过程为:数字水印(X)、水印图像(I*)和密钥/公钥(K)通过数字水印检测算法检测出数字水印或有无水印。
%基于DCT变换的水印算法:将一个随机序列作为水印信号嵌入到图像DCT变换重要分量的幅度成分中(幅值较大的n个系数作为重要分量)。
%定义一个相似函数来检验水印提取是否成功。试验结果表明,该算法具有不可见性,对通常的图像处理,如剪切、缩放、中值滤波、压缩等
%以及噪声干扰都具有一定的鲁棒性。(err)

PNN-classification-prediction
针对变压器的故障诊断,通过概率神经网络对其进行分类。运行程序后,网络输出值和实际值非常接近,很好的实现了对变压器的故障分类。(For the transformer fault diagnosis, we use the probability neural network to classify it. After running the program, the network output value and the actual value is very close, which achieves the good classification of transformer fault .)
