Edited by Freya, VisiHow, Eng, Visihow Admin
You're watching VisiHow. In this tutorial, we're going to show you how to use the "Despeckle" filter on an image in GIMP in Windows 7.
First, click "Filters". It's in the horizontal menu along the top of the window.
Move the cursor to "Enhance" in the menu.
In the expanded menu that appears, click "Despeckle...". A dialogue box will appear with a preview of the image.
You can click and drag the preview to see different areas of the image. You can also click the scrollbars and arrows on the sides.
If you cannot see the preview, ensure that the "Preview" box in the dialogue window is checked.
Next, you can check or uncheck "Adaptive" and "Recursive" under "Median". For this tutorial, only "Adaptive" is left checked.
Below, you can change the "Radius" value. You can do it by clicking and dragging the scroller or by typing a value into the text box. Also, you can click the up and down arrows on the right.
You can then change the "Black level" value in the same way. Use this option to create a painting-like effect on the image.
The "White level" value can also be changed using the scroller, text box, or up and down arrows.
Click "Cancel" if you want to return to the image without making changes.
Once you are satisfied with your changes, click "OK". This will apply them to your layer. A green bar will run across the bottom of the screen, letting you know that the changes are being applied.
