# Tri-state median filter for image denoising

@article{Chen1999TristateMF, title={Tri-state median filter for image denoising}, author={Tao Chen and Kai-Kuang Ma and Li-Hui Chen}, journal={IEEE transactions on image processing : a publication of the IEEE Signal Processing Society}, year={1999}, volume={8 12}, pages={ 1834-8 } }

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… Expand
