Fractional calculus is an abstract idea exploring interpretations of differentiation having non-
integer order. For a very long time, it was considered as a topic of mere theoretical interest …

Some research progress has been made on fractional-order continuous orthogonal
moments (FrCOMs) in the past two years. Compared with integer-order continuous …

In this paper, we propose a new set of discrete orthogonal polynomials called fractional
Charlier polynomials (FrCPs). This new set will be used as a basic function to define the …

A novel cryptosystem of color images is proposed. We defined a multi-channel orthogonal
Gegenbauer moments with fractional order (FrMGMs) in Cartesian coordinates and then …

The single watermarking algorithm for medical images faced several inherent problems like
lack of security. In this paper, a new geometrically invariant multiple zero-watermarking …

Abstract 3D Image representation is an important topic in computer vision and pattern
recognition. Recently, 3D image analysis by fractional-order orthogonal moments has …

Orthogonal moments are used to represent digital images with minimum redundancy.
Orthogonal moments with fractional-orders show better capabilities in digital image analysis …

The Internet of Medical Things (IoMT) plays a vital role in healthcare systems to increase
electronic devices' accuracy, reliability, and productivity. This paper presents fast multiple …

In this paper, we propose a zero-watermarking scheme based on a new set of quaternion
moments called Quaternion Radial Fractional Charlier Moments (QRFrCMs) for the …
