Abstract: In this paper, considering the upper bound and the lower bound of the membership degree and the non-membership degree of the interval valued intuitionistic fuzzy set can be transformed into two corresponding intuitionistic fuzzy sets, we propose the methods of interval valued intuitionistic fuzzy similaritie based on the perspective of intuitionistic fuzzy similarity.It Proves that they satisfy the similarity axiom. Finally, the application of two interval intuitionistic fuzzy similarity in pattern recognition was given.
