Fast and stable computation of higher-order Hahn polynomials and Hahn moment invariants for signal and image analysis

This article presents, on the one hand, new algorithms for the fast and stable computation of discrete orthogonal Hahn polynomials of high order (HPs) based on the elimination of all gamma and factorial functions that cause the numerical fluctuations of HPs, and based on the use of appropriate stabi...
