Abstract

A dedicated hardware system is developed for a recent class of nonlinear hybrid filters called Order Statistics-Rational Hybrid Filters (OSRHF). The performance of these filters is also studied and compared against three effective nonlinear filters from the literature. The application at hand is noise filtering in grey level images. The proposed hardware system uses a residue number system (RNS) to compute the numerator and the denominator of the rational filter. The resulting structure is suitable for direct implementation on FPGAs.
