Abstract :
In this paper, an efficient approach is proposed for the synthesis of an economical digital 2D-IIR filter with high information efficiency, by means of model reduction. As a result a linear phase IIR filter whose frequency response is very close to that of the initial filter and is very suitable for directional filtering and image processing applications.
