have to show YcbCr color space image?

Question

I have to show YCbCr color space using matlab. i can get the YcbCr values but i don't know how to show color space in below format, can any one help me?

Answer 1

I am going to assume for now that you want to make a 3-D scatter plot, because that is what the picture you posted looks like. This is relatively simple, and can be done as follows

pep_rgb = imread('peppers.png');
pep_ycbcr = rgb2ycbcr(pep_rgb);
x = pep_ycbcr(:,:,1);
y = pep_ycbcr(:,:,2);
z = pep_ycbcr(:,:,3);
scatter3(x,y,z);

If you already have the image in YCbCr then you do not have to do the conversion from RGB, this was done in my example to make the default peppers image in matlab is converted to that colorspace
