Abstract
In this paper, we proposed a two-stage switching-based median filter for impulsive noise removal. The noise-detection scheme contains a switching mechanism to identify the characteristic of center pixel. The first stage of our scheme is to identify the center pixel is a really uncorrupted pixel or not. If not, in order to increase the accuracy of noise detection, the center pixel is further discriminated as “uncorrupted pixel”, “impartial impulsive noise “or “impulsive noise “ in the second stage. In the filtering scheme, action of “no filtering” is applied to “uncorrupted pixels”. The output of center weighted median and standard median are respectively applied to “impartial impulsive noise” and “impulsive noise”.
