中文摘要: |
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2.6597,5.2194和0.2065,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2.8656,5.8791和0.3769。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。 |
英文摘要: |
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 2.6597, 5.2194 and 0.2065. Based on CIE 1976L*a*b* color-difference formula, the corresponding results are 2.8656, 5.8791 and 0.3769. The results showed that color differences are basically the same by using CIE DE2000 color-difference formula and CIE 1976L*a*b* color-difference formula which accord with the accuracy of the color scanner characterization. Therefore, CIE DE2000 color-difference formula can be used in the management of scanner characterization. |
