An Improvement to Sluzek′s Moment Invariant Method

CHEN Pei,XU Xiao ming,ZHANG Wei dong,XU Run sheng (Automation Institute,Shanghai Jiaotong University,Shanghai 200030,China)  
In this paper,Sluzek′s method is investigated.Its advantage lies in decreasing moments′ variance and in making full use of discriminating difference between two classes as possible.Its disadvantage is its inability of discriminating two similar classes whose differences lie in the middle.In this paper we will prove in a general form that there is much chance of improving this method,and present a new method.The prototype object is partitioned into n rings of equal moment,and the moment invariants corresponding to these circles are computed,from which some are selected as the descriptors of the objects.Finally,the improving effect of our method is verified by some examples.
