Abstract :
The authors present a method designed to solve the problem of automatic color shade grading for industrial inspection of randomly textured multicolored ceramic tiles. Their grading method is based on the comparison of color histograms and they present results of correctly grading several series of ceramic tiles, the differences of which were at the threshold of human perception
