摘要
基于其局部灰度直方图，提出了一种新的适用于图像型微粒检测的自适应噪声滤波方法。它由中值滤波和特殊的ＯＳ滤波（即α均值滤波、反α均值滤波）等基本滤波器构成。此滤波器在噪声滤除和图像边缘保持两方面都有较满意的性能，而且能简单快速地实现。文中给出了实验的结果。
Based on the local gray level histogram of macroparticle image which is more special than other images, a new adaptive noise filtering method for macroparticle image processing is developed and described in this paper. It is made up of median filter and special order statistic(OS) filters (mean filter and inverse mean filter).This adaptive filter not only has satisfactory performance in both of noiseremoval and edgepreservation of macroparticle image,but also is easy and quick to implement. An example is presented in this paper.
