Abstract

The area, the location of the centroid and the second order moments of a region are determined and expressed in closed-form in terms of the Fourier-coefficients of its boundary function. The orientation of the central axes and the second order central moments can then be easily obtained. Bounds on the perimeter of the region are derived in terms of the Fourier coefficients as well.
