Abstract :
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
