A simple and effective histogram equalization approach to image enhancement
Heng-Da Cheng,Xiangjun Shi +1 more
TL;DR: The multi-peak generalized histogram equalization (multi-peak GHE) is proposed, which is improved by using multi- peak histogramequalization combined with local information to enhance the images effectively.
Journal ArticleDOI
A multiscale morphological approach to local contrast enhancement
TL;DR: The conventional theoretical concept of local Contrast enhancement has been extended in the regime of mathematical morphology and the intensity values of the scale-specific features of the image extracted using multiscale tophat transformation are modified for achieving local contrast enhancement.

An Optimal Fuzzy System for Color Image Enhancement
M. Hanmandlu,D. Jha +1 more
TL;DR: A Gaussian membership function is proposed to fuzzify the image information in spatial domain and a visible improvement in the image quality is observed for under exposed images, as the entropy of the output image is decreased.

Color image enhancement by fuzzy intensification
TL;DR: A Gaussian membership function to model image information in spatial domain and a visible improvement in the image quality for human contrast perception is observed by the reduction in 'index of fuzziness' and 'entropy' of the output image.
