Abstract :
In this paper, a digital image sharpening algorithm is presented by using Riesz potential. First, the definition of Riesz potential is reviewed briefly. Then, the sharpened image is obtained by adding the original image to the scaling Riesz potential of image. Finally, the gray-level and color digital images are used to show the effectiveness of the proposed digital image sharpening method based on Riesz potential.
