MATLAB YCbCr color space is often referred to as YUV.

Hi,
I see the problem
from this link : http://en.wikipedia.org/wiki/YUV
we can also implement the formula by :
RGB = imread('football.jpg');
R = RGB(:,:,1);
G = RGB(:,:,2);
B = RGB(:,:,3);
Y = 0.299 * R + 0.587 * G + 0.114 * B;
U = -0.14713 * R - 0.28886 * G + 0.436 * B;
V = 0.615 * R - 0.51499 * G - 0.10001 * B;
YUV = cat(3,Y,U,V);
imshow(YUV);
