imago features a quick, one-click Median filtering effect to remove image noise and details. The filter searches the radius of a pixel selection for pixels of similar brightness, discarding pixels that differ too much from adjacent pixels, and replaces the center pixel with the median brightness value of the searched pixels. Median filtering is useful to remove shot noise (or salt and pepper noise) on an image.
