A note on the use of windows for two-dimensional FIR filter design
T. Speake, R. Mersereau · IEEE Transactions on Acoustics Speech and Signal Processing · 1981
Using a one-dimensional window as a prototype, a two-dimensional window may be formulated having either a square region of support or a circular one. In this paper we compare the effects of using each of these window formulations for 2-D FIR filter design and present formulas for estimating filter order in terms of design specifications, using a Kaiser window as a prototype.
