Paper Abstract

Discrimination technique between objects with similar colors are presented including traditional color measurement such as Lab and spectral signature. A number of methods have been evaluated for discriminating between different ceramic tile pigments. Ceramic products come in a wide variety with similar colors. Labeling mixups often occur between similar pigments resulting in incorrect products being shipped to customers. Mislabeled products are sometimes installed, since subtle color differences are difficult to perceive, especially with marginal illumination. This will result in direct expenses associated with rectifying these errors as well as customer inconvenience and dissatisfaction.
