概要

• 論文の詳細を見る

• Gamut-mapping experiments were performed to test a set of general-purpose gamut- mapping functions. These gamut-mapping algorithms utilized contrast-preserving scaling functions. These algorithms were tested against the GCUSP gamut- mapping algorithm proposed by Morovic and Luo, 1 which was shown to have very good "universal" gamut- mapping characteristics. The results of these experiments showed that vast improvements were obtained when linear lightness and chroma rescaling functions are replaced with contrast-preserving lightness and chroma rescalingfunctions. For these experiments, the gamut mapping consisted of sigmoidal lightness remapping functions 2.3 followed by either "knee" functions 4.5 or "sigmoid-like" chromatic compression functions.
