Content-Aware Reverse Tone Mapping

We present an image analysis approach for reverse tone mapping of high dynamic range (HDR) content. The goal is to expand the dynamic range of existing low dynamic range content, to be properly shown on modern HDR displays. Most of the existing reverse tone mapping operators fail to offer a good solution in cases where the input images contain large saturated areas. In this paper we present an interactive, higher-level approach to reverse tone mapping. Inspired by the Zone System used in photography, it can also be used as an artistic tool where both the tonal balance and the mood of the final depiction can be adjusted by the user. Potential applications apart from visualization include algorithms for image or scene analysis. Keywords-high dynamic range; reverse tone mapping; image
