Abstract

A novel lattice-ladder structure for the realization of 2D ARMA digital filters is presented. The new realization is based on the 2D AR lattice filter. The algorithm to calculate the lattice-ladder structure coefficients for a given 2D ARMA transfer function is included. The 2D lattice-ladder structure has the properties of orthogonality and modularity as in the 1D case. The lattice-ladder structure might prove useful in 2D adaptive filtering applications.
