Digital-image-processing

说明：  很详尽的傅里叶变换课件，可以学习下，适合初学者。(Fourier transform is very detailed courseware, you can study, one for beginners.)

These four files are intended for addingdeleting nodes and edges in biograph object

This program describes that how the binary data is transmitted by dividing data into frames. it also analyse the Bit Error rate by 16 QAM method and viterbi decoding method.

pid 参数整定代码，使用简单，适合初学者学习使用(The pid parameter tuning code, simple to use, suitable for beginners to learn how to use)

matlab 一些作图划线的基本知识，并且包含一些矩阵运算，方程的求解，附带若干个例子(Basic knowledge of MATLAB, some mapping crossed, and contains a number of matrix calculation, equations, with several examples)

图论算法及Matlab程序代码含注释 很详尽(Graph Algorithms and Matlab code with comment)

this file contains a matlab code for rout planing motion.

彩色图转灰度图++matlab+实现代码，很不错，值得看看！(Color to grayscale++matlab+ implementation code, very good, worth a look!)

对几个混合的常规信号进行傅里叶变换，并将其分离开。然后对几个信号进行时频分析，并求出参数估计的误差。(Conventional signals of several mixed Fourier transform, and separated them. And then the several signal time-frequency analysis, and the parameter estimation error.)

快速自适应非局部sar降斑，bm3d处理图像效果非常不错，但复杂度太高，本文针对bm3d复杂度太高这一缺点，对算法计算方面作出改善；通过源程序文件可以很清楚了解作者思想(Fast Adaptive nonlocal sar Despeckling, bm3d image processing effect is very good, but the complexity is too high, the paper is too high for this shortcoming bm3d complexity of computing algorithm to make improvements can clearly understand what the author thought through the source files)
