im1=rgb2gray(imread('image1_name'));
im2=rgb2gray(imread('image2_name'));
diff_hist=imhist(im1)-imhist(im2);
plot(diff_hist)
Ensure that both have same data type images to get the same range of bins

Yes, if you want. It can be tricky to get findpeaks() to get just the peaks you want and not all of the peaks you don't want, but you can play around with the tons of input parameteters until it gets just the ones you want.
