Abstract
A two-dimensional (2-D) digital filter named a three-terms separable-denominator (3TSD) filter is considered and its spatial-domain design techniques are presented. The transfer function of the approximated filter is obtained by solving a set of bilinear equations iteratively. The 3TSD filter also offers some benefits as an SD filter. For example, the stability of the SD filter is easy to check and the filter is simple to implement. An example is presented to illustrate the utility of the proposed technique
