Spatial-Domain Design of 2-D Quadrantal Symmetric Digital Filters Using Singular-value Decomposition and Singular Perturbation Model Reduction
In this paper a new technique is presented to design low order 2-D quadrantally symmetric HR digital filters. This technique is based on two steps: First, the 2-D impulse response specification (Hankel matrix) is decomposed into k parallel sections, each consists of two cascaded SISO 1-D filters, us...
