摘要：

In this paper, results of the one-dimensional (1D) digital filtering are extended to the two-dimensional (2D) case. it introduces a technique and an algorithm for the computation of the product H(z(1), z(2)2)H(z(1)(-1), z(2)(-1)). The technique is used to find a minimum phase transfer function of a 2D system Such that the previous product matches a given correlation sequence. The algorithm requires less arithmetic operations than the traditional methods. The former is based on a matrix formulation of the product, which is used to investigate the 2D partial fraction decomposition (PFD) and stability.
