| 中文摘要: |
| 为了研究显示器颜色特性化问题，用多项式回归方法对色谱进行了分析，分别采用一次拟合与二次拟合建立了CIERGB到CIEL*a*b*空间的多项式模型。通过色差ΔE和拟合方差σ2的比较，分析了模型的差异。结果表明：多项式模型项数为9和11时，模型效果较为满意，项数为20时，模型出现震荡；并且二次拟合比一次拟合效果好。 |
| 英文摘要: |
| Color characterization of display was studied by using polynomial regression and spectrum analysis. Once fitting and twice fitting between the RGB signals and the L*a*b* values were applied to establish color space conversion model. Through comparing the difference of ΔE and σ2, the differences of the models were analyzed. The results showed that the model can get satisfactory result when number of terms is 9 and 11; twice fitting is better than once fitting; when the term is 20, the model is not stable. |
