Numerous papers have been written regarding techniques to translate color measurements from an RGB device (such as a scanner or camera) into some standard color space. The papers seem to ignore the mathematical "truth"... that the translation is impossible. Do these color transforms work, or under what conditions do they work, and what are the limitations? Why is it that they work (if they do)? In this paper, light emitting diodes (LEDs) are viewed with a color video camera. It is seen that… CONTINUE READING
