Impulse Noise Detection and Filtering in Switching Median Filters
Ashima Mittal, Akash Tayal · 2012
The switching median filter has proved to be quite effective in removing impulse noise. Noise detection plays a significant role in filtering. The proposed algorithm consists of two iterations for detecting noisy pixels. An exhaustive list of simulation results for various types of images shows that the peak signal to noise ratio of the proposed algorithm is high compared to the existing algorithms.
