Abstract:
Spectral power distribution of an illumination is restored using color information in a region of the specific object in an input image and a pre-specified representative surface reflectance of the specific object. The surface reflectance in the region of the specific object is restored from the color information and the spectral power distribution of the illumination. The surface reflectance is corrected using three or more pre-specified reference surface reflectances of the specific object. The color in the region of the specific object is calculated from the spectral power distribution of the illumination and the corrected surface reflectance.
