| 摘要: |
| 在用色彩管理软件以及分光光度仪对显示器进行屏幕的校准和特性化后,以多项式回归算法建立RGB到Lab 颜色转换模型,通过实验分析了多项式回归模型不同项数、不同样本对液晶显示器特性化精度的影响。结果显示,用多项式回归算法建立的三阶三元二十项多项式可以得到色差为2. 5 左右精度较高的预测模型。 |

| Abstract: |
| RGB to Lab color conversion model was established using polynomial regression algorithm after screen calibration and characterization of display with color management software and spectrophotometer. The influence of term number of polynomial regression model and specimen on characterization precision of display was analyzed with experiments. The result showed that polynomial regression prediction model with three orders, three elements, and twenty terms has higher accuracy, with color difference about 2. 5. |
