To improve the spectral image representation and reproduction accuracy, an interim connection space (ICS) was proposed. Three offset functions were defined to make up the wave regions uncovered by the CIEXYZ color matching functions. The XYZLMS ICS was determined based on the CIEXYZ and defined offset functions. The spectral and colorimetric representation accuracy of the proposed ICS was compared to LabPQR and LabRGB with various spectral datasets as testing samples. The results indicated that the proposed ICS outperformed the other two ICS as a whole.
为了提高光谱图像的表示和再现精度，提出了一种中间连接空间（ICS）。定义了三个偏移函数来弥补 CIEXYZ 颜色匹配函数未涵盖的波区。基于 CIEXYZ 和定义的偏移函数确定了 XYZLMS ICS。使用各种光谱数据集作为测试样本，比较了所提出的 ICS 与 LabPQR 和 LabRGB 在光谱和色度表示精度方面的性能。结果表明，所提出的 ICS 在整体上优于其他两种 ICS。
