Detailed Description

The Sharpening category contains filters used to enhance the edges of objects and adjust contrast and shade characteristics.

The high-pass filters used to sharpen an image let high frequencies go through and filter out low frequencies. They enhance the edges of objects in the image, but are very sensitive to noise.

For an introduction to image filtering, see section Image Filters.
