Abstract The similarity measures are essential concepts to discuss the closeness between sets. Fuzzy and intuitionistic fuzzy dealt with incomplete inconsistent data more efficiently. With time in decision-making theory, a complex frame of environment that occurs cannot be specified entirely by these A generalization like Pythagorean set can handle such situation applicability this attracted re...

Matrices play important roles in various areas in science and engineering. The classical matrix theory can not solve the problems involving various types of uncertainties. That type of problems are solved by using fuzzy matrix [14]. Later much works have been done by many researchers. Fuzzy matrix deals with only membership values. These matrices can not deal non membership values. Intuitionist...

This work introduces a program to enhance images taken in low-light. Fuzzy set theory is creating significant shift image processing. Interval-valued intuitionistic fuzzy sets (IVIFS) based on constructed from are used In the proposed method, first given low-light fuzzified by normal fuzzification. Then converted an interval-valued image. will be enhanced after applying contrast limited adaptiv...
