摘要
采集1000样本点用多项式回归方程法建立RGB到L*a*b*颜色空间的转换模型,计算色差,分析多项式回归方程法的优点及缺陷。实验结果表明:多项式回归方法计算方法简单,易于逆运算,且运行速度快。
The conversion model of RGB to L＊a＊b＊ color space was established with data of 1000 samples and polynomial regression equation. Color difference was calculated and the advantage and disad- vantage of polynomial regression algorithm was analyzed. The experimental results showed that the poly- nomial regression algorithm is simple, easy for reverse operation, and fast in calculation.
