TLDR
In this article, the design of two-dimensional linear-phase FIR digital filters by transformations of one-dimensional (l-D) filters was discussed, using a technique first presented by McClellan.Abstract:
This paper discusses the design of two-dimensional (2-D) linear-phase FIR digital filters by transformations of one-demensional (l-D) filters, using a technique first presented by McClellan. His original transformations are generalized and several algorithms are presented for the design of the generalized transformations. Examples are included to demonstrate, the versatility of the design method.read more

Convergence Properties Of A Constrained 2-D Adaptive Digital Filter
TL;DR: A new adaptive 2-D digital filter is presented in which the filter is deterniined by a 1-D FIR prototype, and hence the computational complexity of the coefficient up-date algorithm has an order of complexity O(M), rather than O( M/sup 2/).

Design of FIR filters to complex frequency response specifications
TL;DR: It is shown that the design of FIR digital filters for a general class of phase-magnitude error tolerance specifications is equivalent to the requirements for minimax synthesis of a particular two-dimensional linear-phase FIR filter.

Two-dimensional windows
TL;DR: It is shown that good two-dimensional windows can be obtained by rotating good one- dimensional windows, that is, if w(x) is a good symmetrical one-dimensional window, then w sub 2(x,y) = w(square root of (x squared + y squared)) is aGood circularly symmetrical two- dimensional window.

J. Hu,Lawrence R. Rabiner +1 more
TL;DR: The theory for designing finite-duration impulse response (FIR) digital filters can readily be extended to two or more dimensions using linear programming techniques, and several of the issues involved in designing two-dimensional digital filters are discussed in this article.
