Fractional-order quaternion exponential moments for color images
作者：
Highlights：
• The properties of fractional-order and integer-order radial basis functions are analyzed and compared in depth.
• FrEMs are constructed on the basis of fractional-order radial basis functions.
• FrQEMs are constructed based on the quaternion theory.
• The experimental results show that FrQEMs have great performance.
• A novel kind of fractional-order radial basis functions is constructed.
