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。 After calibrating and characterizing the display by color management software and spectrophotometer, the RGB to Lab color conversion model was established by polynomial regression algorithm. The different items of polynomial regression model were analyzed experimentally. Different samples were used to characterize the liquid crystal display The impact of precision. The results show that using the polynomial regression algorithm to establish the third-order twentieth and twentynomial polynomial can get the color difference of about 2.5 with higher accuracy prediction model.
