Which of the following represent the correct equations for trichromatic coefficients?(a) x=X/(X+Y+Z), y=Y/(X+Y+Z), z=Z/(X+Y+Z)(b) x=(Y+Z)/(X+Y+Z), y=(X+Z)/(X+Y+Z), z=(X+Y)/(X+Y+Z)(c) x=X/(X-Y+Z), y=Y/(X-Y+Z), z=Z/(X-Y+Z)(d) x=(-X)/(X+Y+Z), y=(-Y)/(X+Y+Z), z=(-Z)/(X+Y+Z)This question was addressed to me by my school principal while I was bunking the class.My enquiry is from Color Fundamentals in portion Color Image Processing of Digital Image Processing |

Answer» CORRECT answer is (a) X=X/(X+Y+Z), y=Y/(X+Y+Z), z=Z/(X+Y+Z) Explanation: Tri-stimulus values are the amounts of red, green and blue NEEDED to form any particular color and they are denoted as X,Y and Z respectively. A colors the SPECIFIED by its trichromatic coefficients x, y & z: =X/(X+Y+Z), y=Y/(X+Y+Z), z=Z/(X+Y+Z). |
