Abstract :
In this paper we present an efficient technique for the design of linear phase 2-D FIR filters using SVD method. We show that by appropriately choosing the order of the 1-D subfilters in the parallel legs of the 2-D filter structure, a sizable reduction in the number of multiplier coefficients is achieved. A local search optimization method is then utilized to obtain finite wordlength coefficients
