The fast recursive computation of Tchebichef moment and its inverse transform based on Z-transform
2013

In this paper, we derive a simplified recurrence relationship to compute Tchebichef polynomials based on Z-transform properties. ...
Experimental results show that both the proposed algorithms to compute TMs and inverse Tchebichef moments (ITMs) perform better than existing methods in term of computation speed. ...
