Minimum mean brightness error contrast enhancement of color images using adaptive gamma correction with color preserving framework

Abstract

In this paper, we propose an efficient method to enhance contrast of digital images. Image contrast enhancement is a pre-processing step that improves efficiency of other image dealing applications such as computer vision and pattern recognition. The proposed method enhances contrast and brightness of given image using the gamma correction and weighted probability distribution of luminance pixels. Experiments results show that the proposed method is able to enhance contrast of all type of color images without much affecting its visual and color information.
