This paper presents a comparison of two-dimensional finite area impulse response (FIR) digital filters designed using three popular design methodologies - through the use of windows, through the use of transformations of one-dimensional designs, and through the use of optimal Chebyshev design techniques. In addition the comparison includes filters designed for processing both rectangularly-sampled and hexagonally-sampled data. The filters are compared with respect to ease of design and the efficiency of the resulting implementation.
