基于亮度保持的子图像加权对比度增强
Brightness-Preservating Based Weighted Sub-Images for Contrast Enhancement
摘要
Abstract
In this paper, an efficient contrast enhancement method based on brightness-preserving is proposed. This method defines the outputdmage as the weighted sum of the two sub-images generated by BBHE. At the same time, a brightness-preserving way, based on the mean brightness of the input image and two sub-images, to calculate two weight coefficients is given. It is shown through the experimental results that the proposed method can preserve the mean brightness with higher accuracy than many other brightness-preserving methods while enhancing the contrast efficiently.In addition, the proposed method in this paper is quite simple which makes it meet the requirement of real-time.关键词
