gaussn

This code is used to cut selected part of the image that is of course after you decompress.   And run the code in the image circle separated.

说明：  胡氏不变矩，matlab程序，稳定运行，能区分两张图片的不同(Hu invariant moments, matlab program, stable operation, can distinguish between two different images)

Rayleigh fading with + BER Calculation for Independent Gaussian random variables with zero mean and unit variance

Moment s Legendre algorithm

这是用matlab写的dct代码用于图像的信息的隐藏和提取。。部分老师写的哦。(This is used to write the DCT matlab code for the image and extract the hidden information. . Oh part of the Writing Teacher.)

matlab应用于数学认真阅读然后直到其具体功能(applied mathematics matlab read until its specific function and then)

说明：  这个是RS的原代码，几个文件一起仿真，很有用的(This is the original RS code, with the simulation of several files, very useful)

关于MATLAB图形用户界面(GUI)初学者指导教程系列，有较详细的说明和指导(On the MATLAB graphical user interface (GUI) Beginners Guide series, has a more detailed explanation and guidance)

对信号进行设定层数的小波分解。只输入参数信号、层数及小波类型即可，里面有验证程序。(Decompose the signal with the layer you set.Just input parameter signal, the number of layers and wavelet types.)
