Efficient Contrast Enhancement Using Adaptive Gamma Correction With Weighting Distribution
TL;DR: An automatic transformation technique that improves the brightness of dimmed images via the gamma correction and probability distribution of luminance pixels and uses temporal information regarding the differences between each frame to reduce computational complexity is presented.
Proceedings ArticleDOI
Efficient contrast enhancement using adaptive gamma correction and cumulative intensity distribution
TL;DR: Experimental results show that the proposed histogram modification method produces enhanced images of comparable or higher quality than previous state-of-the-art methods.
