United Hu Moment and Their Application to TV Image Recogniton
Peng He · Computer Engineering and Applications Journal · 2006
The influence of scale factor on Hu moment invariants in discrete is analysed,Hu's invariant moments based on regions and Chen's invariant moment based on boundary are extended,a new kind of invariant moments is proposed,which can be applied to both regions and boundaries,and its scale transformation is invariance in discrete,it is more common than Hu invariant moments.Experiments show that new invariant moments is effective and valuable.
