In this work, a novel nonlinear filter, called tri-state median (TSM) filter, is proposed for preserving image details while effectively suppressing impulse noise. We incorporate the standard median (SM) filter and the center weighted median (CWM) filter into a noise detection framework to determine whether a pixel is corrupted, before applying filtering unconditionally. Extensive simulation results demonstrate that the proposed filter consistently outperforms other median filters by balancing…

Impulsive noise filter using median- and partition-based operation
A novel filter is proposed in this work to remove noise and preserve fine details from the impulse-corrupted images based on median and partition operation that outperforms many filters in terms of both noise suppression and detail preservation.
