Cellular Neural Networks with UBN and MVN

Abstract

Cellular Neural Networks (CNN) with UBN and MVN as the basic neurons (respectively, CNN-UBN and CNN-MVN) are considered in this chapter. A brief introduction to the CNN, and an observation of the related applied problems are presented. It is shown that the use of MVN and UBN as the basic CNN neurons may extend their functionality by implementing mappings described with non-threshold Boolean and multiple-valued threshold functions. Some problems of image processing, which may be effectively solved using CNN-UBN and CNN-MVN are considered: precise edge detection, edge detection by narrow direction, impulsive noise filtering, multi-valued nonlinear filtering for noise reduction and frequency correction (extraction of image details).
