Model Based Steganography Source code by Matlab

this is a powerfull code in mix and hidden picture in another pic for staginography

PSO算法，用matlab，用C++语言的源代码(PSO algorithm, using matlab, using C++language source code)

Tsai Calibration method

小车-倒立摆的平衡控制问题，由强化学习方法来求解，参考sutton《强化学习》一书(cart-pole balancing control problem，reinforcement learning algortihm is used here， please refer to Sutton s book ,named 《reinforcement learning》)

实现拉格朗日插值，和用拉格朗日插值拟合函数(Lagrange interpolation to achieve, and the fitting function with the Lagrange interpolation)

说明：  matlab代码，新进的emd分解工具，比小波效果好(Matlab code, the new EMD decomposition tool, is better than wavelet)

对信号进行短时傅立叶变换，输出的序列在进行循环平稳处理，最后用mesh函数进行3维画图。()

说明：  EEMD将特殊幅值下的高斯白噪声引入到分解的过程，可以消除上包络和下包络之间存在的拟合误差，从而很好地避免不同尺度下IMF的模态混叠现象，(EEMD can eliminate the fitting error between the upper envelope and the lower envelope by introducing the Gaussian white noise with special amplitude into the decomposition process, so as to avoid the mode aliasing of IMF at different scales,)

基本的数字信号处理matlab源代码，包括IIRdemo.m，nyquist_aliasaudiodemo.m，sinfreqdemo.m等(Basic digital signal processing matlab source code, including IIRdemo.m, nyquist_aliasaudiodemo.m, sinfreqdemo.m etc.)
