三角剖分技术在颜色空间转换技术方面的应用

Application of 3D Triangulation Technique in Color Conversion

引入三角剖分技术,不仅成功解决了设备色域范围的确定问题,而且实现了三维查表插值法的分区。结合三维查找表四面体插值法,优化搜索算法,建立颜色转换模型。经216块全色域样本色靶检验,其转换精度与传统的Neugebauer方程反求转换模型相比,色彩转换精度高、效率高,取得了良好的建模效果。

3D triangulation technique was introduced into color transformation. The determination problem of equipment color gamut was solved successfully and the partition of 3D-LUT interpolation method was realized. Color conversion model was established with combination of 3D-LUT tetrahedral interpolation meth- od and through optimization of searching algorithm. 216 full color target sample were tested and the results were compared with traditional Neugebauer equation reverse conversion model. The results showed that the conversion precision and efficiency of the new model is higher than that of the traditional one.
