Segment Based Constructive Median for Removal of Impulsive Noise

In this paper we proposed an efficient mechanism for removal of impulse noise from the digital images. The proposed filter is Segment based Constructive median (SCM), is integration of a cascaded easy to implement impulse detector and a detail preserving noise filter. In the first phase ,the impulse detector classifies any possible impulsive noise pixels. In the second phase filtering replaces the detected noise pixels. Apart from that the filtering phase employs fuzzy reasoning to deal with uncertainties present in local information. Contrary to many existing filters that only focus on a particular impulse noise model, the SCM filter is capable of filtering different kinds of impulse noise – the random-valued and/or fixed-valued impulse noise models. ------------------------------------------------------------------------***----------------------------------------------------------------------
