Abstract:
In this paper, a digital image sharpening method using Riesz fractional order derivative (RFOD) and discrete Hartley transform (DHT) is presented. First, the definition of Riesz fractional order derivative is reviewed briefly. Then, the DHT interpolation method is described. Next, the RFOD, DHT interpolation and Mach band effect are used to construct a digital image sharpening algorithm. Finally, several numerical examples are demonstrated to show the effectiveness of the proposed digital image sharpening approach.
