sharpen images and remove excessive dots and distortion. Please
read through the following explanations and examples to learn

contrast by making dark edges lighter and light edges darker.
Blur More: see Blur.
Sharpen allows you to sharpen the edges within an image by
making the edges in an image more distinct. The Sharpen filter
