Abstract: A method for the classification of white colour,based on the three-dimensional Euclidean distance is proposed.First of all,a white panel was used as the standard measure of the standard light source in which the standard image was thaken,the RGB tri-color respective values of the color were got,and then translated into color space CIELUV.Re-classification of the color in the same light source was conducted to obtain their RGB points.The three-dimensional Euclidean distance was used to measure th...
