Intuitionistic Fuzzy Similarity Measure for Generalized Fuzzy Numbers and its application in Fingerprint Matching
Abstract
ABSTRACT Fuzzy geometric measures have been found to reflect the spatial ambiguity of an image. Therefore, the study of similarity of fuzzy numbers is crucial in decision making. In this work, an intuitionistic fuzzy similarity measure (IFSM) has been proposed to calculate the degree of similarity of generalized fuzzy numbers (GFNs). The IFSM has been developed by integrating the concept of centre of gravity (COG) points and intuitionistic fuzzy difference of distance of points of fuzzy numbers. Properties that are relevant for a similarity measure have also been derived for the proposed IFSM. Further, a few pattern sets available in literature have been compared and it was observed that the IFSM provides a very intuitive quantification. Finally, the similarity measure has been applied for a fingerprint matching problem.
