Abstract:

为了研究跨媒体复现中CIECAM02的背景预测性能,基于双目同时的视觉匹配实验,获得显示器软拷贝与不同中性灰背景下硬拷贝的视觉匹配数据,分析了中性灰背景对颜色外貌的影响,并利用实验数据对CIECAM02的背景预测性能做了评价.实验结果表明:背景明度主要诱导色块明度和彩度的变化,对色相略有影响.明度、彩度、色相三者中,明度改变最明显,背景越暗,诱导色块越亮,随着背景明度变暗,背景明度的诱导绝对量趋于稳定;彩度变化幅度不大,但是不符合色诱导规律;而色相基本不变.CIECAM02可以解释背景明度对明度的诱导现象,但不能解释对彩度的诱导现象,且背景参数不能准确反映背景对颜色的影响,有待于修正.
