H. S. N. Murthy, D.R. Reddy, P. Reddy · IEEE Transactions on Geoscience and Remote Sensing · 1985
In this paper, the least square inverse (LSI) polynomial with respect to a multidimensional polynomial is defined. The definition of a form-preserving 1-D polynomial with respect to an n-D polynormal is given. Then a stabilization theorem useful in the design of n-D recursive filters through the LSI approach is stated and proved.
