Parity Symmetry and Univalence of Complex Lucas, Faber and Gegenbauer Polynomial Operators for Intensity-Domain Image Enhancement

In this study, three global tone mapping operators are built from classical polynomial families to enhance low contrast documentation images, their behaviour fixed in advance by symmetry rather than chosen by taste. Lucas, Faber and Gegenbauer polynomials are generated by a recur...
