利用LFSR生成伪随机序列（m序列） 对待隐藏的图像进行加密然后利用线性插值的方法隐藏于载体图像中。 代码很完整 用的是MATLAB7.0(Use LFSR to generate pseudo-random sequence (m sequence) to treat encryption to hide the image and then use linear interpolation method of hidden images in the vector. Complete code is used in MATLAB7.0)

已修改调试，可以运行.有图像结果，易以观察结果(it can be used in matlab, because it have amend.)

白噪声和有色噪声的生成方法，参数可以由用户自己设定(White noise and colored noise generation method, the parameters can be set by the user)

多普勒信号有很多种，我这里上传的是通过常规函数构造出一个理想的多普勒信号，多普勒信号是用其频移来进行计算的，一般是激光干涉仪等出来多普勒信号(Doppler signal there are many, I am here to upload a laser Doppler interferometer signal out through conventional function construct an ideal Doppler signal, the Doppler frequency shift signal is carried by its calculations)

一个主成分分析方法的matlab实现，比较经典齐全的源码(A matlab Implementation of principal component analysis)

对测试信号进行emd 分解，计算其在各个频带中的能量分布(The EMD of the test signal is decomposed, and the energy distribution in each frequency band is calculated)

一个聚类程序，基于贝叶斯最小错误率的判别，效果挺好的。(A clustering procedure, based on Bayesian minimum error rate of the discriminant, the effect quite good.)
