A Hybrid Approach for Efficient Color Gamut Mapping

Ultra High Definition (UHD) and High Definition (HD) Television standard recommendations support different color gamuts with the HD gamut much smaller than that of the UHD one. To adapt UHD content to the restricted gamut of HD televisions, a process known as gamut mapping is required. This gamut mapping projects out-of-gamut colors inside the targeted color gamut. Gamut mapping can be performed in any color space and using different projection methods. In this paper, we present a hybrid gamut mapping approach which selects one combination of color space and projection method for each UHD color representable. The selection is based on the CIE Delta E2000 metric. Results show improvements in terms of CIE Delta E2000 when comparing original and projected colors over existing methods.
