摘要
采用三维查找表的转换方法,建立了RGB-CIELab色彩空间转换模型,取得了较好的实验结果,模型转换的色差都小于3,在人的视觉不敏感范围内。比较研究了4种插值算法模型的精度,结果表明:随着将立方体的分区细划,转换精度越来越高。
RGB-CIELab color space conversion model was established using three-dimensional look-up table method.Experimental results showed that the color difference of the color transformation is less than 3,which is under human visual sensitive range.The accuracy of four models of different interpolation algorithm was compared.The results showed that the conversion accuracy increases with the size of cube partition decrease.
