A novel algorithm of infrared image enhancement based on fuzzy sets theory is proposed in this paper. First, Pal and King's algorithm was analyzed and its drawbacks were summarized. Then, the local fuzzy entropy of image was calculated for determining the threshold. On this basis, the new membership function of fuzzy was defined and infrared image was enhanced effectively by fuzzy enhancement transformation,...
Presently, many researches have been carried out on rough set based data reduction. However, this method encounters a problem when dealing with real-valued data and fuzzy information. By lucubrating the theory of fuzzy rough set and utilizing the definition of information entropy presented in literature [5], the information entropy model of fuzzy rough set has been constructed. Then the conditional...
