HDR Image Rendering by Combining Single-Scale Local and Global Tone Mapping Operators

摘要

A Common task in computer graphics is the tone mapping of digital high dynamic range images to low dynamic range display devices such as monitors and printers. Various techniques have been proposed for compressing the dynamic range while retaining important visual information. The goal of those techniques has been to reproduce images that capture the visual appearance of scenes. In this paper, we emphasize that a really desirable image can not be obtained only by accurately reproducing the perceived scene in the image, and develop a new tone mapping technique for creating excellent images with combining local and global operators. Then we discuss the proposed technique theoretically and empirically by comparing with conventional tone mapping operators. The resulting algorithm is simple and produces good results for a wide variety of high dynamic range images.
