摘要
依据 BFD,RIT- Du Pont,Witt1999和 L eeds等 4组色差评估实验数据集 ,在色貌模型 CIECAM97s修订版的基础上建立了一种优化的均匀色貌空间 U CAS.用综合统计指标 P′F/ 3评价该色貌空间 ,并引入优化的明度修正因子 .结果表明 ,其均匀性接近德国 1999年的色差标准 DIN99,并优于 CIE1976年推荐的 CIEL AB.
An optimized uniform colour appearance space named UCAS is deduced based on the revised edition of colour appearance model CIECAM97s according to BFD, RIT DuPont, Witt1999 and Leeds colour difference evaluation data sets. Tested by a synthetically statistical index P ′ F/3 with the introduction of an optimized lightness correcting factor, the results show that the uniformity of UCAS is close to the new German standard DIN99 issued in 1999 and better than CIELAB recommended by CIE in 1976.
