Résumé : |
Colorimetric matching is employed under a series of virtual illuminants to produce more controllable and equalised colour-difference results under multiple illuminants. A method based on weighted principal component analysis of different artificial lights and the weighted mean is used to create a series of virtual illuminants. The weights were selected in a manner to create the virtual illuminants that benefit from the impact of a given illuminant, while the effects of other light sources on the formation of desired illuminants were also considered. The generated virtual illuminants were implemented in a colorimetric colour-matching trial. Using this method, by choosing suitable weights for different lighting conditions, more balanced colour-difference values were presented in the data set than was expected. The advantages of the suggested method were evaluated by the matching of a collection of 135 woollen samples under different virtual illuminants. |
