about conversion of color spaces

 Accepted Answer

rgb2ycbcr
MATLAB YCbCr color space is often referred to as YUV.

but YUV color space is not exactly similar to Ycbcr color space.there are different conversion equations for that like U=0.493(B-Y),V=0.877(R-Y) and conversion matrix also. so How I can impement these equations for finding YUV color space.
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);
Thanks alot.
