【摘要】 通过定性分析Munsell色样集在不同光源下的von Kries校正系数随色样不同而变化的现象,本文提出了一种按照图像所属区域类型调整von Kries系数的颜色校正方法,并给出了区域判定规则及各区域von Kries系数确定方法。在GCCD测试数据集上的实验结果表明,该方法有较好的效果。更多还原

【Abstract】 It is shown that the von-Kries coefficients of Munsell ColorChart vary with the colour samples under different illuminants.A method is proposed for colour correction,which adjusts the von Kries coefficients according to the type of image region.The criterions for deciding the regions and the related von Kries coefficients are given.Experimental results on the GCCD datasets indicate that this method is better than others.更多还原
