Color image enhancement by fuzzy intensification
Madasu Hanmandlu, D. Jha, R. Sharma · 2002
A Gaussian membership function to model image information in spatial domain has been proposed in this paper. We introduce a new contrast intensification operator which involves a parameter t for enhancement of color images. By minimizing the fuzzy entropy of the image information, the parameter t is calculated globally. A visible improvement in the image quality for human contrast perception is observed, also demonstrated here by the reduction in 'index of fuzziness' and 'entropy' of the output image.
