This code calculates frame difference to detect moving object in video

在HHT变换后，可用于计算平均周期，即用整个序列的长度分别除以极大值点个数和极小值点个之后求平均(average period prediction)

数值分析要求：第二题编成命令文件即可，其中阶乘可以单独编成函数文件在命令文件中调用，也可以直接在你所编的命令文件中利用循环语句直接计算； 第四题编成通用的程序，建议编成函数文件。提示：可以把多项式的系数和所需要求解的点设为参数。(Numerical Analysis of requirements: the second title of the command file can be compiled, which can factorial function into a separate file in order to call the document can also be made directly in your document, use the command loop direct calculation into fourth title common procedures, the proposed document into function. Tip: polynomial coefficients can be requested and the required parameters set point solution.)
