Implementation of 2-D separable-in-denominator digital filters for real-time processing

Abstract

In this paper, the general decomposition of separable in denominator 2-D discrete systems is reported. In sequel, several novel realizations for Separable -in-Denominator 2-D digital filters are presented. The number of required multipliers and additions for the implementation of these structures are reduced in comparison with the previously reported structures[4],[5]. The proposed realizations possess high degrees of parallelism,modularity which are suitable for VLSI design and implementation[l3].
