Abstract

In this paper, we present a novel segmentation based method for displaying high dynamic range image. We segment images into regions and then carry out adaptive contrast and brightness adjustment using global tone mapping operator in the local regions to reproduce local contrast and brightness and ensure better quality. We propose a weighting scheme to eliminate the boundary artifacts caused by the segmentation and decrease the local contrast enhancement adaptively in the uniform area to eliminate the noise introduced. We demonstrate that our methods are easy to use and a fixed set of parameter values produces good results for a wide variety of images.
