Re: How does the noise reduction software - Noiseware works?

"Typically, noise reduction is done by applying a "median filter" to every
pixel in the image."

Not true. Most kinds of the noise encountered in image processing do not
have a suitable distribution for median filtering. For noise removal,
median filtering is typically used in rare cases where the noise is
"impulsive," "salt and pepper," or "speckled." These noise distributions
have sharp peaks at the median and/or fat tails near +- infinity.
