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。

Firstly, it explains the development of various kinds of optical fibers, including the standard single mode fiber (SMF), dispersion shifted fiber (DSF), and non zero dispersion fiber (NZDF), it also explains the operating wavelength windows, including 1.

本文分两部分：先介绍光纤的研制发展过程，讲到标准单模光纤（ＳＭＦ）、色散移位光纤（ＤＳＦ）和非零色散光纤（ＮＺＤＦ），又讲到单模光纤的几个波长窗口，主要是１。
