Title: | 2-D FIR Eigenfilters: A Least-Squares Approach | Authors: | Pei, Soo-Chang Shyu, Jong-Jy |
Issue Date: | Jan-1990 | Publisher: | Taipei:National Taiwan University DEPT ELECT ENGN | Journal Volume: | VOL. 37 | Journal Issue: | NO. 1 | Start page/Pages: | - | Source: | IEEE Transactions on Circuits and Systems | 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. |
