New Trends in Tone Mapping
The previous chapter presented an overview of tone mapping. The operators presented are typically tailored for a specific goal when reducing the dynamic range of an HDR image such as preserving local/global contrast, matching the perception of the HVS, etc. A more recent trend is to develop generic TMOs that are flexible and can simulate the existing ones [247], or to mix different TMOs [38,429], or TMOs that adapt the output to be suitable for any display device [242]. In addition, there is now increased attention by researchers in the management of colors. The compression of the HDR input for the low dynamic range of the display has typically been performed only on the luminance range. The color ratio is kept, ...
