I want my input data to be an image that has been converted to XYZ color space to represent on color space instead of having to enter input data, please help me, thanks!
my code ( input data is entered manually )
How do I make the input data an image that has been converted to XYZ space?
% generate two clusters of color points
rgb = min(abs(randn(2000,3).*[0.5 0.3 0.1] + [0 0 0]),1);
rgb = [rgb; 1-rgb];
xyz = rgb2xyz(rgb);
hold on;
% plot the points
view(3); grid on;
axis equal
axis([0 1 0 1.1 0 1]);

To convert an image to an XYZ space (or, an m-by-n-by-3 array which RGB color space uses, according to here), you can use the imread function:
X = X = im2double(imread('images.jpg'));
R = X(:,:,1); % Only Red channel
G = X(:,:,2); % Only Green Channel
B = X(:,:,3); % Only Blue Channel
Then, you can easily continue with rgb2xyz(X);
