abstract = {This paper presents some algorithms for approximating two-dimensional convolution operators of size n {\texttimes} n, n odd, by a product, or sum of products, of 3 {\texttimes} 3 convolutions. Inaccuracies resulting from the approximation as well as from fixed point computation are discussed and examples are given.},
