How to use the applet

There are three images located on the screen. The first image is the input image. The both next ones demonstrate the effect of an median-and an averaging filter respectively.You can change the input image when you press the -button. The new picture will be filtered automatically. With the -button you can define the dimension of the filter mask. You can also add Gaussian noise to the image () or salt it by pressing the salt & pepper button (). If you do so observe the difference of median and averaging filters! When you move the mouse pointer over one of the filtered images, a zoomed area of the active mouse position is produced on the small images on the right side.
