最速下降法是以负梯度方向作为下降方向的极小化算法，本程序用该方法求解n元正定二次函数的极小值-Steepest descent method is based on the negative gradient direction as a decline in the direction of the minimization algorithm, this procedure using this method for solving n-positive definite quadratic function of the minimum

在图像处理中，就必须得到更好的图像质量。所以在这里实现了中值滤波的代码及去噪算法。

验证后可以使用的DetectLines算法，可以使用在图像处理之中，尤其在对图像进行校正操作时，效果非常好

AffineTransform类描述了一种二维仿射变换的功能，它是一种二维坐标到二维坐标之间的线性变换，保持二维图形的“平直性”（译注：straightness，即变换后直线还是直线不会打弯，圆弧还是圆弧）和“平行性”（译注：parallelness，其实是指保二维图形间的相对位置关系不变，平行线还是平行线，相交直线的交角不变。大二学过的复变，“保形变换/保角变换”都还记得吧，数学就是王道啊！）。仿射变换可以通过一系列的原子变换的复合来实现，
