This is known as … WebThe online calculator below allows you to apply a box filter to an image. To do this, the handbook Box filters introduces several well-known filters: for sharpening, edge detection, blurring, anti-aliasing or smoothing, embossing, and gaussian blurring. You can immediately apply them to the image and see the result.
