摘要
在基于样本测量值的基础上,为快速描述出设备的色域边界,拟合得到不同色相面的边界曲线,采用区域均匀分割算法,测量样本的L*a*b*值后,对CIE L*a*b*均匀颜色空间进行区域均匀分割,并对其中的空集区域插值,最后利用存储的色域边界描述矩阵中的点集信息拟合出边界曲线。插值后,矩阵点集信息更加完整,描述的色域边界连续性和平滑性增强。该算法在计算精度上可以实现色域剖面边界描述,经插值后,等色相面的边界拟合效果更好。
Based on the sample measurement, this paper describes the gamut boundary of device, and fits some gamut boundary lines in different hue plane. After measuring the sample’s L＊a＊b＊ value, the segment maxima method is used to segment the CIE L＊ a＊ b＊ uniform color space, and interpolated some date to the empty area among them. Finally, using the gamut boundary description matrix which has stored a set of points, this method fits out boundary curves. Interpolation matrix become more complete, the continuity and smoothness of gamut boundary curves reinforce, so the fitting curves fulfill gamut boundary description. This method can basically achieve the color gamut section boundary description and the fitting results in same hue plane show better after inter-polating.
