Question

What do you mean by the smoothing and sharpening filter example?

Answer 1

Smoothing Filters. Smoothing filters are used to enhance noisy images (at the expense of blurring). This filter generates the average over a 3 x 3 area of the image. The technique is also called moving window averaging.

Sharpening Filters. Sharpening, which can help emphasize details and enhance the edges of objects in an image, is critical when post-processing many types of images.
