This paper treats the problem of constructing inverse two-dimensional (2-D) causal systems with inherent delay (M, N) for Attasi-type 2-D systems.First, the notion of an MN-delay inverse is introduced for 2-D causal systems. This is considered to be a generalization of an L-delay inverse for 1-D systems given by Sain and Massey. A necessary and sufficient condition for the existence of an MN-delay inverse is then shown for Attasi-type 2-D systems.Finally, a method is presented for constructing an MN-delay inverse for these systems.
