Abstract

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.
