采用由RGB控制信号到参考色空间变换的方法形成了CIELAB空间中均匀分布的色域表面描述点集;进一步采用三角形网格化和插值技术,形成了适于色域特性分析和色域压缩的色域描述。通过采用优化的变换和在 CIELAB L*a*b*空间中的插值技术,提高和改善了色域表面的确定精度和平滑性。该描述可给出色域体积、原色和二原色合成色的色度等色域特性指标,以及一定参量下的二维色域图。
The uniform color gamut surface descriptor point set in CIELAB space is formed by the method of spatial transformation from RGB control signal to reference color space. By using the technique of triangle meshing and interpolation, a method of color gamut analysis and color gamut compression Color gamut description. By using optimized transforms and interpolation techniques in CIELAB L * a * b * space, the accuracy and smoothness of the color gamut surface are improved and improved. This description gives an indication of the color gamut properties of the color gamut volume, the primary colors, and the two primary colors, as well as the two-dimensional color gamut map for a given parameter.
