Tool introduction

The principle of image sharpening is to enhance the edge of the image by introducing an artificial sharpness. It is done by increasing the contrast of adjacent pixels, which makes the edges appear sharper. The process is usually done by a Gaussian blur, which is a type of blur that applies a Gaussian function to each pixel in the image. The Gaussian blur reduces the contrast between adjacent pixels, which makes the image appear softer. In order to sharpen the image, the Gaussian blur is then reversed and the contrast between adjacent pixels is increased. This makes the edges of the image appear sharper.
