Design of digital Riesz fractional order differentiator
This is a research branch of fractional calculus and filter design. The closed-form designs of Riesz fractional order differentiator (FOD) are presented. The variable Riesz FOD is implemented by the Farrow structure. The Riesz FOD provides the better image quality than the conventional FOD in image sharpening applications.
