Design of 2-D FIR filters using McClellan transformation withgenetic algorithms

摘要

A powerful genetic algorithm approach is proposed in order todetermine the optimal coefficients of the McClellan transformation. Itcan be used to design any arbitrary shape transformation contours to mapfrom 1D prototypes to 2D finite impulse response (FIR) filters veryeffectively. In this paper, we present design methods for 2D fan filterswith arbitrary slope, elliptical filters, elliptical filters witharbitrary orientation, circular filters and diamond-shaped filters indetail. There are several numerical examples given to demonstrate theusefulness and the efficiency of this proposed method
