Abstract.  The classical circularity measure that considers the relationship between the shape area and the shape perimeter is sensitive to noise and limited for shapes with boundary defects (which lead to a large increase in perimeter). We propose a recent and generic method for shape circularity measure. The proposed method derives from radial moments and satisfies the desirable properties of circularity measures. Compared with the classical circularity measure and Hu moment invariants based method, the new measure is robust to noise and performs better in the case of shapes with boundary defects. Experimental results also show the superiority of the proposed method.
