2D FIR Wiener filter realisation using orthogonallattice structures
Ahmet Hamdi Kayran, Ender M. Ekşioğlu · Electronics Letters · 2000
A new realisation algorithm for 2D FIR Wiener filters is proposed. The reduced-order 2D orthogonal lattice filter structure is used as the principal component as in the 1D case. A numerical example is included to verify the formulation.
