Abstract: Definition of a new image invariant feature named normalized moment of inertia(NMI) feature is proposed by using physical Aconceptions, analysis on the invariability of NMI feature is given in this paper. newapproach to target recognition based on image NMI feature is presented. Experimental results show that the NMI feature of image has the ability of anti-tonal and geometric distortions(translation, rotation and scaling, TRS), and its extraction method is simple. Moreover, the presented target recognition approach is more efficient compared with the traditional NProd and image invariant moment matching algorithm. Conclusion and suggestions for future development are discussed in the final part of this paper. ;;;
