Determine the CIE chromaticity coordinates of a point given 𝐶1 = 0.14,0.4,2 ; 𝐶2 = 0.51,0.6,1 . Find the third colour 𝐶3 Solution x1= 0.14, y1= 0.4 x2=0.51,y2=0.6 L1=1,L2= 2 Therefore k1= L1/y1 =2/0.4 =5 k2=L2/y2= 1/0.6 =1.67 The third Coordinates x3 and y3 x3=0.23 y3=0.45 L3= L1+L2 =2+1=3 Therefore third coordinates are (0.23,0.45,3) Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Gamma Correction of a Colour Image Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu output image of Gamma Correction Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu Edited & Complied Dr. Rajesh Muthu 1.
