Sharpen filters

The Sharpen filters do the opposite of the Blur filters and increase
the contrast of adjacent pixels, making images appear sharper and
more focused.
The three sharpening filters (Sharpen Low, Sharpen Medium, and
Sharpen High) improve clarity. The Sharpen High filter has a
greater sharpening effect than the Sharpen Medium filter, which in
turn has a greater sharpening effect than the Sharpen Low filter.
