The nonsymmetric half-plane (NSHP), recursive, two-dimensional (2-D) digital filters are described. Such a filter is characterized by a linear, shift-invariant (LSI), constant coefficient difference equation that is nonanticipatory in one index but is recursively computable for a fixed direction of recursion. A computer-aided iterative approach is described for the design of a stable, NSHP, 2-D digital flter approximating a specified magnitude response.
