ARTIFICIAL INTELLIGENCE FILE, WHICH CONTAINS A LESSON ABOUT HOUGH TRANSFORM AND A BASIC ALGORITH IN MATLAB DOING SKELETIZATION AND HOUGH PRINCIPLES.EXCEL CONTAINING A MATRIX ABOUT THE APPLICATION

说明：  计算4阶通计量的程序，程序可以包含在你自己的工程中，做高阶统计必备！(Calculation 4-order through measurement procedures, procedures can be included in your own projects, so higher-order statistics must have!)

matlab学习刚起步，可以进步很快，大家一起学习一下(Matlab is a very useful software, we study together)

用曲线拟合的方式估计线性调频信号的初始频率及其调频斜率。得到的效果比较好。(Curve fitting way to estimate the initial frequency and chirp rate of the linear FM signal. Get better.)

说明：  能将一张大海的图和一张海鸥的图叠加在一起，同时进行边缘检测，如果海鸥图超出大海的边界，能自动进行裁剪。(Can a sea gulls and a figure added together, simultaneously the edge detection, if the sea gull beyond the border, can be cut.)
