数字图像处理canny以及hough算法

本程序为模型预测控制程序的一种，自带实时计算更新模块，完成循环仿真。(This procedure is belong to the model predictive control algorithm, with real-time update module calculation to complete the cycle simulation.)

说明：  BP神经网络实现手写数字识别，以包含字库，字库内容有改动，方便测试识别结果(BP Neural Network realizes handwritten numeral recognition to include a font, the content of the font is changed, and it is convenient to test the recognition results.)

实现混沌倍周期分岔，分岔后最后达到混沌状态。(Chaotic period-doubling bifurcation, and finally reach the chaotic state after the bifurcation)

high pass filter for frequency domain

实现EMD分解，用于信号处理，分解出IMFs分量(Of EMD for signal processing, decomposition of the IMFs component)

LMS Classical algorithm

本程序是QPSK信号在瑞利衰落信道下的仿真，已经过本人验证，适合初学者(This procedure is QPSK signal simulation in Rayleigh fading channel, I have been verified, suitable for beginners)

此程序用于振动性能分析，求震动信号的相频、相频特性。(This program performance for the vibration analysis, find the frequency of vibration signal phase, phase-frequency characteristics.)

包括图像分析的四部分代码：matlab扩散和高斯函数，线性扩散，线性复扩散，非线性扩散。(It contains four parts： [1]MATLAB function:diffusion.m gauss.m [2]Linear diffusion Applying linear diffusion to images creating linear scale-space. MATLAB code: demo_lin.m Image: haifa1.bmp [3]Linear complex diffusion Applying linear complex diffusion creating Gaussian and Laplacian scale-spaces. MATLAB code: demo_cmplin.m [4]Nonlinear diffusions: Perona-Malik ["Anisotropic diffusion"] Catte et al. regularization of P-M Complex ramp-preserving diffusion Nonlinear edge preserving diffusions.The classical Perona-Malik process: the value of the diffusion coefficient is reduced near edges estimated by the first derivative. Best applied to step edges. A regularized version by Catte et al- the gradient estimation for controlling the process is smoothed by a Gaussian. Proved to be mathematically well-posed. Ramp preserving complex diffusion- best for ramp-type edges. Results are smoother with almost no staircasing effects. MATLAB code: demo_nldif.m Image: ct_scan.bmp)
