网络管理系统基于古典的NMS方法，提出了一个二维的边缘检测器，它能给出边缘位置精确的亚像素位置，同时其计算量很低，应用起来非常方便。

　　NMS方法主要用于检测局部的最值。

-The network management system based on Classical NMS method, a two-dimensional edge detection, it gives the exact edge positions of the sub-pixel position, while the amount of calculation is very low, it is very convenient to application. The NMS method is mainly used for most of the detection of local value.
