How to copy one image to another (blank) pixel by pixel?

Xc = imread('IM1.jpg');
tam = size(Xc)
sizex = tam(1);
sizey = tam(2);

blank = ones(sizex,sizey,3);
for i=1:sizex
    for j=1:sizey
        for d=1:3
            blank(i,j,d)=Xc(i,j,d);
        end
    end
end
imshow(blank);

why isn't it working? any ideas?

Answer 1

[David Sanchez]

    Xc = imread('Arinaga+29+de+mayo+de+2013-3.jpg');
    [sizex sizey sizez]= size(Xc);

    blank = zeros(sizex,sizey,sizez);
    for i=1:sizex
        for j=1:sizey
            for d=1:3
                blank(i,j,d)=Xc(i,j,d);
            end
        end
    end

%%%%%the new addition

    image(uint8(blank));

that's it! thanks a lot!

Alternatively, a more general case:

blank = zeros(sizex,sizey,sizez,class(Xc))

You should try this:

Xc = imread('IM1.jpg');
blank = Xc;
imshow(blank);
