I believe by band intensity you mean to separate R,G,B components from the image and get individual intensities. To do that, get individual 2-D matrices from the 3-D matrix. So, if 'img' is a variable containing the color image data.
R = img(:,:,1);
G = img(:,:,2);
B = img(:,:,3);
Hope this is what you are looking for.
