A novel hyperbolic intuitionistic fuzzy divergence measure based mammogram enhancement for visual elucidation of breast lesions

•An intuitionistic fuzzy divergent measure based contrast enhancement approach.•Hesitant score metric is derived from source and complementary mammogram images.•Fuzzy membership grade is modified using hyperbolic regularization and entropy.•Enhanced mammogram is generated by applying Werner’s AND/OR operators.•The model is computationally effective.
