Centroid, Centroid From Edge Vectors, and Shape Descriptor Using only Boundary Information

A simple algorithm is presented to obtain the area and the centroid of a plane homogeneous feature, by using only the coordinates of the boundary points. The algorithm also allow higher order moments to be calculated. From such centroid, and the centroid from edge vectors, we defined a shape descriptor invariant to Rotation, Scale, and Translation transformations. This parameter is able to characterize features with asymmetric distribution of roughness or reentrants.
