| 摘 要： | 采用支持向量回归机(SVR)建立了RGB色空间到CIE Lab色空间的转换模型,分别采用CIE DE2000与CIE 1976L*a*b*色差公式对模型精度进行色差计算。采用CIE DE2000色差公式得到的测试组色差平均值、最大和最小值分别为2.659 7,5.219 4和0.206 5,采用CIE 1976L*a*b*色差公式得到的测试组色差平均值、最大和最小值分别为2.865 6,5.879 1和0.376 9。实验结果表明,CIE DE2000与CIE 1976L*a*b*色差公式计算的色差值基本一致,均符合彩色扫描仪特征化精度要求,可将CIE DE2000色差公式用于扫描仪特征化管理中。

| Abstract: | Transformation model of RGB color space to CIE LAB color space was established by using support vector regression(SVR).CIE DE2000 and CIE 1976L*a*b* color-difference formulas were used in calculation of accuracy of the model.Based on CIE DE2000 color-difference formula,the average,maximum and minimum color differences of text set are 2.659 7,5.219 4 and 0.206 5.Based on CIE 1976L*a*b* color-difference formula,the corresponding results are 2.865 6,5.879 1 and 0.376 9.The results showed that color differences... |
