Local contrast stretch based tone mapping for high dynamic range images

摘要

This paper presents a local tone mapping method to render high dynamic range images on conventional displays. We adaptively stretch contrast in local regions to reproduce local contrast. In order to avoid halos, we use bilateral filtering to smooth the image prior to the contrast stretching operation. Our method is fast and easy to use, and the experiment results show that the technique can produce good results on a variety of high dynamic range images
