A Fuzzy Logic Control Based Approach for Image Filtering
Farzam Farbiz, Mohammad Bagher Menhaj · Studies in fuzziness and soft computing · 2000
SummaryThis chapter is devoted to introduce a new filtering approach based on fuzzy-logic control concepts with the properties of removing impulsive noise and smoothing out Gaussian noise while, simultaneously, preserving edges and image details efficiently. The main idea behind the proposed filtering approach is that each pixel is not allowed to be uniformly fired by each of the fuzzy rules. In this chapter, different modifications of this filtering approach (Iterative Fuzzy Control based Filter — IFCF) named by MIFCF, EIFCF, SFCF, SSFCF, FFCF, AFCF and ACFCF are presented along with some test experiments highlighting the merit of each filter. From the experimental results we may list the concluding remarks of the proposed filtering approach: high quality of edge preserving ability, high filtering quality especially for complex images, multiplicative noise removing property for IFCF based filters, floating point free calculations and very fast performance for FFCF based filters.
