Asift-MATLAB

该程序是基于小波变换的熵谱，用来提取时间序列的周期成分。熵谱相对于小波谱来说在提取周期成分上有一定优势(The program is based on spectral entropy of wavelet transform to extract time series of the periodic component. Entropy is relative to the small spectral component in the extraction cycle, there are some advantages)

matlab读取YUV文件，有需要的可以看看 (Matlab read YUV video, detailed and comprehensive, there is a need to have a look)

本书全名《精通MATLAB-综合辅导与指南》，是西安交通大学李人厚、张平安与1997年译校后出版的，文章对MATLAB基本使用方法进行了介绍，并通过举例的方法使内容浅显易懂(The full name of the book " Mastering MATLAB-comprehensive counseling and guidance," Li Xi' an Jiaotong University is one thick, Ping-An Zhang translation school in 1997 after the publication of the article on the basics of using MATLAB are described, and examples of the way through the contents of plain and easy to make understand)

该程序可以用来进行波谱分析，非常直观地图示频谱信息。(The program can be used for spectral analysis, spectral information very intuitive icon.)

模糊优化线性潮流，线性处理与模糊优化的综合潮流处理算法。 (Linear trend of the fuzzy optimization, linear processing and fuzzy processing algorithms to optimize the overall trend.)

IEEE30节点配电网标准系统图，可运行,用于配电网建模，电能质量分析(IEEE30 node distribution network standard system diagram, you can run.)

MATLAB 程序，基于GUI界面设计的PCM调制、编码的仿真，这个是用界面设计开发，为大家在编写程序提供了帮助(MATLAB program, PCM modulation, coding simulation-based GUI interface design, this is the interface design and development, provide help in the preparation of the program)

说明：  利用巴特沃斯高通滤波、理想高通滤波、高斯高通滤波处理图像，根据需求使图像得到锐化，并比较他们的效果。(Use bart wo high-pass filter high-pass filter, ideal, gaussian high-pass filter processing images, according to demand makes the image get sharpening, and compare their effect. )

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)
