This contribution is intended as a survey of the existing fuzzy (or fuzzy related) ltering techniques for multichannel (and color in particular) images. We propose a classi cation of all these approaches to color image processing into four categories, based on the importance that fuzzy theory receives during the lter design: crude fuzzy, fuzzy paradigm based, fuzzy aggregative and fuzzy inferen...

This paper studies a fuzzy graph rewriting with single pushout approach from a viewpoint of fuzzy relational calculus. Two possible kinds of matchings for fuzzy graph rewritings are given, namely, a rigorous matching which just generalizes matchings for crisp (or ordinary) graph rewritings, and an "-matching which represents rather ambiguous or fuzzy one. Finally the pullback structure of fuzzy...

Local Zika virus transmission in the United States involving one or both of the known vector species, Aedes aegypti and Ae. albopictus, is of major concern. To assist efforts to anticipate the risks of transmission, we developed an Excel spreadsheet tool that uses vector and virus temperature thresholds, remotely sensed maximum temperature, and habitat suitability models to answer the questions...

We propose a deductive extension of the spreadsheet paradigm as the basis for an automated assistant for the daily reasoning and decision-making needs of computer users, in the same way as a spreadsheet application such as Microsoft Excel assists them every day with calculations simple and complex. Users without formal training in Logic or even Computer Science can interactively define logical ...
