Abstract :
A simple algebraic criterion is presented to check if a given 2-D MIMO (multi-input/multioutput) filter described by a nonsingular transfer matrix is in fact a cascade of two 1-D filters with a minimal number of inputs and outputs. The criterion offers the advantage that whenever a filter is found to be separable, it is almost trivial to construct the two 1-D filters
