1) knife edge filtering
刀口滤波
1.
Universally analyzed and discussed in this paper is the visualization of inhomogeneous phase distribution of phase objects with spatial zero frequency filtering and knife edge filtering method.
对空间滤波法的零频滤波与刀口滤波显示位相型物体的非均匀位相分布进行较为普遍且详尽的分析讨论，并给出一些实验结果。
2) filter windows
滤波窗口
1.
The proposed filter calculated the noise rate of the corrupted image based on the minimum local entropy, and utilized the noise rate to determine the size of filter windows and the number of pixels to be brushed off in the filter windows of Alpha-trimmed mean filter, and then used the average of leaved pixels gray as the output of the filter.
提出一种基于图像最小信息熵的自适应滤波算法,利用局部信息熵最小的办法估计图像中的噪声感染程度,从而自适应地确定修正后的Alpha均值滤波器中滤波窗口的大小和去掉灰度最大和最小的像素个数,然后进行滤波。

本文提出一种基于图像最小信息熵的自适应滤波算法,利用局部信息熵最小的办法估计图像中的噪声感染程度,从而自适应的确定修正后的Alpha均值滤波器中滤波窗口的大小n和去掉灰度最大和最小的像素个数d,然后进行滤波,实验结果表明此算法较现有的中值滤波和均值滤波嚣的滤波能力有显著提高,而且在图像的局部特征和细节保持方面优于现有的滤波算法,并克服了修正后的Alpha均值滤波器的非自适应性的弱点。

5) double windows filtering
双窗口滤波
6) Running Windows Filters Method
窗口滤波方法
补充资料：刀口腐蚀
knifelinecorrosion：含有稳定化元素（诸如钛、铌等）的不锈钢在其与焊缝熔化区接触的部位，在腐蚀性介质中因晶界腐蚀而产生一种深而窄的缝隙，形如刀口，故称“刀口腐蚀”。
