Welch法得到的功率谱估计。 设计滤波器对白噪声滤波后的功率谱。(Welch method of power spectrum estimation. Design filters with the noise power spectrum after filtering.)

说明：  这是基于帧差法对运动目标检测的代码 希望对大家有用(This is based on frame difference of the moving target detection code)

说明：  上载文件为Matlab环境下的高斯以马尔科夫模型例程，很好用(document on the Matlab environment for the Gaussian Markov model routines to good use)

Steganography using Matlab

使用MP将图像稀疏分解并且精确重构，其中使用2D的GA原子(MP will use the image sparse decomposition and perfect reconstruction, in which the GA using 2D atomic)

The purpose of this book is to teach basic programming concepts and skills needed for basic problem solving, all using MATLAB® as the vehicle. MATLAB is a powerful software package that has built-in functions to accomplish a diverse range of tasks, from mathematical operations to three-dimensional imaging. Additionally, MATLAB has a complete set of programming constructs that allows users to customize programs to their own specifications.

根据卷积定理，通过移位相加求和的方式计算离散序列的卷积(According to the convolution theorem, summed calculated by shifting the sequence of discrete convolution)

说明：  常用方差分析方法，有单因素一元，多因素等(Common anOVA methods include single factor, single factor, multiple factor, etc)

获取已知输入信号的上、下包络的matlab程序(ENVELOPE gets the data of upper and down envelope of the known input signal)

利用 matlab的GUI 环境编写 多项式曲线拟合程序，及其界面，由于参数的输入是实时的、拟合过程可以实时显示，因而使用非常方便。(Using matlab GUI to prepare the environment polynomial curve fitting procedures, and its interface, as input parameters in real time, the fitting process can be real-time display, which is very convenient to use.)
