If you want to treat only images borders, you can't apply filter to the whole image. The solution to get the wanted effect is as follows:

  1. Duplicate layer (LayerDuplicate Layer) and select it to work on it.

  2. Apply Tileable Blur filter with a 20 pixels radius to this layer.

  3. Select all (Ctrl+A) and reduce selection (SelectionShrink) to create a border with the wanted width.

  4. Give a feathered border to the selection by using SelectionFeather.

  5. Delete selection with Ctrl+K.

  6. Merge layers with LayerMerge down.
