Matlab画地球（高质量同等比例下的地球）(This is matlab file to draw earth)

matlab中运用hough变换，设定恰当的阈值，将超过阈值的点在三维空间标示出来&将三维参数矩阵根据半径的不同做成不同的帧，制作成视频(hough transform matlab in use, set the appropriate threshold, will exceed the threshold point in three-dimensional space marked out & three-dimensional parameter matrix made of different frames depending on the radius, made into video)

这是2014年在自然杂志上发表的密度峰聚类的代码(This is 2014 in Nature magazine published the density peak clustering code )

这是一个关于齿轮的齿顶圆和齿根圆半径的计算程序，先将图片预处理和二值化，然后进行边缘检测求出圆心，最后用平均法求出半径。(This is an addendum on the gear tooth root radius circle and the calculation procedure, the first image preprocessing and binarization, edge detection and then find the center of a circle, with the final calculated average radius.)

说明：  绘制星座图的程序，主要要是QAM的仿真，希望大家看看。基于小波的星座图仿真(Constellation diagram drawing program, the main if the QAM simulation, let us look. Wavelet-based Constellation Simulation)
