Spectral reconstruction using iteratively reweighted-regulated model from two illumination camera responses

This document shows spectral reflectance data and RGB values of 380 samples for spectral estimation, which includes 5 databases: 1) Spectral reflectance of ColorChecker semigloss chart (CCSG, 140 patches), 2) Spectral reflectance of ColorChecker DC matte chart (CCDC, 240 patches including 232 mattes, and 8 glossy patches), 3) RGB values of ColorChecker semigloss chart (CCSG, 140 patches) , 4) RGB values of ColorChecker DC matte chart (CCDC, 240 patches including 232 mattes, and 8 glossy patches), 5) Spectral Power Distribution value of  3500K & 6500K illumination conditions.
