Abstract :
The authors present a design method for two-dimensional centrosymmetric zero-phase finite-impulse-response (FIR) filters, via the generalized McClellan transform. An in-depth study of the transform involved in the design method reveals a number of useful properties. These properties are used in the design method for an optimal definition of the generalized McClellan transform coefficients. The method can be applied to the design of classical 2-D FIR filters, yielding filters that are very close to the 2-D ideal specifications
