A Novel Algorithm for 2D-IIR Filters Synthesis via 2D-FIR Filters Model Reduction
Authors: ,
Abstract: A digital 2D-FIR filter with linear phase, circularly symmetric with respect to the origin of the frequency plane, is designed using the two-dimensional windowing method. An economical filter with high information efficiency is obtained by applying the balanced realization method to this full-order filter. The result is a linear phase IIR filter whose frequency response is very close to that of the initial filter.
