Question
Please give me correct solution.
Below is a small 4-by-4 pixel colour image.
(1.0, 0.0, 0.0)
(0.5, 0.7, 0.6)
(0.5, 0.9, 0.7)
(0.3, 0.6,0.3)
(1.0, 0.9,0.9)
(0.9,0.7,0.6)
(0.1, 0.7, 0.0)
(0.9, 0.5, 0.4)
(0.4, 0.3, 0.3)
(0.4, 0.2, 0.9)
(0.5, 0.8,0.0)
(0.8, 0.3, 0.7)
(0.3, 0.6,0.3) (0.3, 0.6, 0.4)
(0.6, 0.6, 0.1)
(0.6, 0.1, 0.8)]
Where each vector shows the (R,G,B) values at the corresponding pixel. This image is to be down-sampled to become a 2-by-2 pixel colour image. Calculate the
pixel values of the down-sampled image for the R colour-channel.
