The MedianActivity Class is available in LEADTOOLS Document and Medical Imaging toolkits.
Changes the color of each pixel in an image to the median color of the pixels in its neighborhood. This is similar to the AverageActivity activity, but it is used for noise reduction, rather than a blur effect.
