CIE L~*a~*b~*颜色模型在烟草中的应用研究进展

Research Progress of CIE L~*a~*b~* Color Model Application in Tobacco

烟草颜色特征指标主要依靠人工经验获取,主观性强,存在一定的不稳定性。CIE L~*a~*b~*颜色模型色域宽阔、色彩分布均匀,常用于烟草(含烟草制品和卷烟材料)颜色参数等的测定与分析。对CIE L~*a~*b~*颜色模型在烟叶产地、烟叶品种、烟叶分级等方面的应用进行综述,并对其在烟草中的应用前景进行展望,为烟草分级、采购、原料控制提供参考。

The color characteristic indexes of tobacco are mainly obtained by artificial experience,which is subjective and unstable.CIE L^*a^*b^* color model is very suitable for the determination and analysis of color parameters of tobacco(including tobacco products and materials) because of its broad color gamut and uniform color distributions.The application of CIE L^*a^*b^* color model in tobacco production area,tobacco varieties,tobacco classification etc.was reviewed,and the application foreground of CIE L^*a^*b^* color model in tobacco was prospected,which could provide reference for tobacco grading,procurement and raw material control.
