What is it about?

Effective fixed value impulse noise filter robust to high and low noise densities

Why is it important?

Yields excellent results and outperforms other filters in the literature. Also avoids filtering images without noise unlike standard nonlinear filters. Performs incremental denoising. Does not replace the noisy pixel but rather gradually modifies it to recover the original or approximate original pixel values.
