Accepted answer

It's practically just like how it sounds:

denominator = sqrt(sum(yourImage(:).^2));
outputImage = double(yourImage) / denominator;

I trust you were honest when you didn't tag this as homework, because I'm not supposed to just give you the answer if it was your homework. Mark the answer as Accepted once you verify that the code works.
