用边缘检测算法检测的圆的像的边缘点，并用多元线性回归求出椭圆的方程，然后按照我们的模型中提供的方法，求出每个圆心的像的位置-Using edge detection algorithm to detect the edge of the image circle points, and multiple linear regression equation of the ellipse obtained, and then follow the model provided by our met

高斯列主元消去法，用来解多元线性方程组，从而解决相关的方程组问题-Principal component Gaussian column elimination method used to solve a multivariate linear equations to solve the equations

MNF是一种多元线性统计变换方法，MNF变换的基本思想就是通过构造原始观测数据各分量的线性组合，将观测数据中包含的信号与噪声两部分尽可能分离，使得线性映射变量的信噪比最大化。MNF变换本质上含有两次叠置处理的主成分分析变换。-MNF is a statistical multiple linear transformation method, the basic idea is the MNF transform raw observations by constructing a linear
