Im trying to normalize an image from 0 to 1,after having used rgb2gray. However using mat2gray and im2double is only giving me 0 and 1 values, nothing in between. I also need to use the equation (I-min(I))/(max(I)-min(I)) and somehow I still can only get zeros and ones.

mat2gray() and rescale() will both work. If you're only getting 0 and 1 then you have only two gray levels in your image. Post your image so I can check it.
