At the latest JVT meeting we presented the YCoCg color space, including its simple transformation equations relative to RGB and its improved coding gain relative to both RGB and YCbCr. We also discussed the reversibility of RGB to YCoCg conversion process in the case that two additional bits of precision are used for YCoCg relative to the precision used for source RGB data. In this proposal, we additionally present a variation of this color space, which we call YCoCg-R. The YCoCg color space has been applied to JPEG XR image compression and to texture compression through the YCoCg-DXT algorithm.
