According to the authors' abstract: ''A technique is developed for approximating a two-dimensional (2-D) causal recursive digital filter using a strictly causal filter. This is done via singular value decomposition of two finite Hankel matrices and a certain mapping technique. Since the resulting filter is simpler than a causal filter and is separable in the denominator, the implementation is advantageous and the stability check is very easy. An example is given to illustrate the utility of the proposed technique.''
