利用Hu矩对26个英文字母进行提取和识别(Using Hu moments of the 26 English letters are extracted and recognized)

说明：  基于傅里叶变换的去除图像纹理方法。通过去除频域高亮区域来消除纹理，保留低频信息。(Based on Fourier Transform method to remove the image texture. Highlighted region by removing the frequency domain to eliminate the texture, retain low frequency information.)

通过恢复低秩矩阵得到显著性图，其中详细的运用了mean-shift算法，可以很好的了解mean-shift算法的使用，同时还包含了RPCA算法。(Significantly through the recovery of low rank matrix diagram, which detailed the use of mean-shift algorithm, can be a very good understanding of the use of the mean-shift algorithm, also contains RPCA algorithm.)

MATLAB GUI设计学习手记（第二版）源程序 第8章 本书推荐的学习方法： 1）若您是一个MATLAB初学者，且有充裕的时间来学习GUI设计，您可以从本书的第1章开始循序渐进地学习。 2）若您是一位MATLAB初学者，且时间非常紧迫，建议您先学好第1章，然后依次学习第4章、第5章和第6章，其他章节请根据项目需要有选择性地学习。 3）若您已经掌握了MATLAB的基础语法知识，有一定的MATLAB编程基础，也请浏览一下第1章的内容，尤其是专题分析部分。然后先学习本书第4、5和6章，其他章节请根据项目需要有选择性地学习。 4）若您是一位MATLAB GUI方面的专家或老师，您可以将本书作为一本教学的参考书，本书内容全面、讲解详实、代码精炼，是不可多得的GUI宝典。 (MATLAB GUI design learning Hearts (second edition), Chapter 8 of the book recommended source learning methods: 1) If you are a MATLAB beginners, and there is plenty of time to learn GUI design, you can start from Chapter 1 of the book The step-by-step learning. 2) If you are a MATLAB beginners, and the time is very tight, it is recommended that you first learn to Chapter 1, followed by learning Chapter 4, Chapter 5 and Chapter 6, in other sections based on project needs selective learning . 3) If you have mastered the basic grammar of the MATLAB, the MATLAB Programming Fundamentals, please visit the Chapter 1, in particular thematic analysis section. First learning book chapters 4, 5 and 6, then the other chapters selective learning based on project needs. 4) If you are an expert or teacher of a MATLAB GUI, you can book as a teaching reference books, the book is comprehensive, explain the detailed, refined code, is a rare GUI canon.)

中频数字正交采样，并进行滤波，得出基带信号(IF quadrature sampling and filtering)

H桥DC-DCPWM变换器matlab simulink仿真模型(The H bridge the DC-DCPWM converter matlab simulink simulation model)

本代码包含了多个MATLAB经典程序，其中有：滤波器，线性变换，图像处理等(This code contains a number of MATLAB classical procedures, including: filters, linear transform, image processing, etc.)

说明：  基于LQR和PID的倒立摆小车控制，希望有需要的人能用到(Based on the control of the inverted pendulum trolley based on LQR and PID, I hope that those in need can use it)

本程序应用于选择图像处理区域，然后进行绿色分析。还可以求得绿色站的比重。(This procedure applies to select image processing region, and then proceed to the green analysis. Can also find the proportion of Green Point.)
