%0 Journal Article %J Computer Vision, Graphics, and Image Processing %D 1988 %T Some algorithms for approximating convolutions %A O'Leary, Dianne P. %X This paper presents some algorithms for approximating two-dimensional convolution operators of size n × n, n odd, by a product, or sum of products, of 3 × 3 convolutions. Inaccuracies resulting from the approximation as well as from fixed point computation are discussed and examples are given. %B Computer Vision, Graphics, and Image Processing %V 41 %P 333 - 345 %8 1988/03// %@ 0734-189X %G eng %U http://www.sciencedirect.com/science/article/pii/0734189X88901077 %N 3 %R 10.1016/0734-189X(88)90107-7
