keywords: rotation moment invariants, complete and independent basis
General method for constructing independent and complete set of rotation invariants of arbitrary orders by means of complex moments is described. It is shown that for any set of invariants there exists relatively small basis by means of which all other invariants can be generated. The basis of the 3rd order moment invariants is constructed explicitly and its relationship to Hu's invariants is studied. Based on this study, Hu's invariants are shown to be dependent and incomplete.
