The Motion Blur filter blurs in a specific direction at each point, which allows you to create a sense of motion: either linear,
radial, or rotational.
Finally, the Tileable Blur filter is really the same thing as a Gaussian blur, except that it wraps around the edges of an image to
help you reduce edge effects when you create a pattern by tiling multiple copies of the image side by side.
Note
Tileable Blur is actually implemented by a Script-Fu script that invokes the Gaussian blur plug-in.

15.2.2.1 Overview
Figure 15.8: The Blur filter applied to a photograph
(a) Original (b) Blur applied
The simple Blur filter produces an effect similar to that of an out of focus camera shot. To produce this blur effect, the filter takes
the average of the present pixel value and the value of adjacent pixels and sets the present pixel to that average value.
Filter advantage is its calculation speed. It suits big images.
Filter disadvantage is that its action is hardly perceptible on big images, but very strong on small images.
