Fuzzy - Based Filtering of Multichannel Images ( Invited Paper )

Multichannel signal processing using digital signal processing techniques has received increased attention due to its importance in different information technology applications such as mul-timedia technology and telecommunications. Our objective in this paper is to provide a review for the reader who may be well versed in DSP, and to introduce some existing fuzzy (or fuzzy related) filtering techniques for multichannel (and color in particular) images, for the reader who is just beginning in this field of artificial intelligence. We present a general formulation based on fuzzy concepts, which allows the use of adaptive weights in the filtering structure, and we discuss different filter designs. Some examples illustrate the strong potential of fuzzy nonlinear filters for multichannel signal applications, such as color image processing.
