[A new adaptive filtering method for micro-particle image processing]

Based on the local gray level histogram of macro-particle image which is more special than other images, a new adaptive noise filtering method for macro-particle image processing is developed and described in this paper. It is made up of median filter and special order statistic (OS) filters (alpha-mean filter and inverse alpha-mean filter). This adaptive filter not only has satisfactory performance in both of noise-removal and edge-preservation of macro-particle image, but also is easy and quick to implement. An example is presented in this paper.
