Medical Image Enhancement through Intuitionistic Fuzzy Sets

A contrast enhancement of medical, color and Grayscale, images via intuitionistic fuzzy sets on different types of entropy – based methods have been studied. Fuzzy set concept counts vagueness in the formula of the membership functions. Intuitionistic fuzzy sets count fuzziness in the membership and non-membership functions. Various entropy – based methods are applied as enhancement operators, and the enhanced image is the one that is interpreted based on the used intuitionistic fuzzy membership function. As medical images include too much ambiguity, this study demonstrated that the intuitionistic fuzzy sets are shown to be useful tools implemented for medical image enhancement. To determine the efficiency of the studied methods, experimental results associated with the handled entropy methods are presented in thesis. Experiments on several image libraries indicate that the spatial entropy method among several applications performs better than it is alternatives.
