Generator code

In en:MATLAB:

RGBimage = imread('barns_grand_tetons.jpg');
[height,width,depth]=size(RGBimage);

% Newer versions of matlab need outputimage=zeros(height*4,width,depth,'uint8');
outputimage=uint8(zeros(height*4,width,depth));
for w=1:width,
  for h=1:height,
    outputimage(h,w,1) = RGBimage(h,w,1); %Copy R, G and B for normal image
    outputimage(h,w,2) = RGBimage(h,w,2);
    outputimage(h,w,3) = RGBimage(h,w,3);
    outputimage(h+height,w,1) = RGBimage(h,w,1); %Copy R only for first component
    outputimage(h+(2*height),w,2) = RGBimage(h,w,2); %G only for second component
    outputimage(h+(3*height),w,3) = RGBimage(h,w,3); %B only for third component
  end
end

image(outputimage);

imwrite(outputimage,'rgb_separation.jpg','jpeg');
