Nonlinear smoothing

General linear and nonlinear smoothing in an intensity image can blur corners seriously, so its difficult to detect corners by a multi scale approach.

对灰度图进行一般线性和非线性平滑会极大程度地模糊拐角，使得多尺度方法难以用于拐角检测。

With the data of nonlinear processing and data smoothing function, rapid automatic correction, self diagnostic message.

具有数据非线性处理及数据平滑功能，快速自动多点校正，自诊断信息提示。

In the smoothing process of image, it is very important for nonlinear filter to reserve fringe detail of image while filtering noise.

图像平滑处理中，如何在去除噪声的同时完整地保留图像边缘细节一直是非线性滤波算法研究的热点问题。
