Abstract
The l-D eigenfilter approach is extended for designing 2-D
FIR filters. By minimizing a quadratic measure of the error in the 2-D
frequency band, an eigenvector of an appropriate matrix is computed to
get the filter coefficients. This method is not only simple but is also
optimal in the least-squares sense. Several numerical design examples of
2-D arbitrary shape filters are used to illustrate the effectiveness of this
approach.
