In the smoothingprocess 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。

At last, it proposes a series of improved algorithm, holding the boundaries shape effectively by a "weak leakage" model in the smoothingprocess.
最后,本文给出了该模型的一些改进,利用“弱泄漏”模型来使在平滑过程中对边缘形状进行有效的保持。

Substantially, this method is a smoothingprocess resulted from the mathematical skills of weighted least square fitting, combining with the iterative method for correct indexing.
