matlab语言写的细胞自动机数字水印算法(matlab language of cellular automata Digital Watermarking Algorithm)

STEGO IMAGE MATLAB CODE

低通滤波器，对数据进行平滑，也叫做最小二乘法，Savitzky-Golay算法(a particular type of low-pass filter, well-adapted for data smoothing, and termed variously Savitzky-Golay, least-squares, or DISPO (Digital Smoothing Polynomial) filters. Rather than having their properties defined in the Fourier domain and then translated to the time domain, Savitzky-Golay filters derive directly from a particular formulation of the data smoothing problem in the time domain)

说明：  本程序是求解一厚壁圆筒的matlab程序，采用平面等参单元计算(This program is a thick-walled cylinder matlab solving procedure for the calculation of plane isoparametric element)

采用修改的Yule－Walker方程来计算ARMA模型的参数，注意，是针对随机信号； (calculat parameters for ARMA model)
