Salt & Pepper Noise and Median Filters, Part II – The Code

In my first post on salt & pepper noise (hereon s&p noise) and median filters I gave an overview what s&p noise is, why it occurs, and how we can tackle getting rid of it. As discussed, median filters are especially effective at removing s&p noise from images. At the end of the last post I promised to delve into the code behind generating an image with s&p noise and the filters to remove it. Read on for code extracts and explanations.
