  What you have shown in your first posting is the formula for an image's central moments.  If you consult the Wikipedia referenc I gave you, these can be used to compute the eta scale invariant moments, and these in turn can be used to compute the eight different Hu moments in accordance with the formulas given there.

  I don't understand your question where you wrote, "hu moments give values in exponentials".  The only exponentials involved are the "orders" associated with the various moments.  What exactly are you asking?
