A New Scheme for Impulse Detection in Switching Median Filters for Image Filtering
Umesh Ghanekar, Awadhesh Kumar Singh, Rajoo Pandey · 2007
As the performance of the filtering system depends upon the accuracy of the noise detection scheme, in this paper we present a new scheme for impulse noise detection based on the local contents of the selected spatial window. In the proposed scheme we also use a noise estimator to decide the number of iterations during the first pass of the filtering. The efficacy of the proposed filter has been confirmed by extensive simulations.
