Abstract :
This paper develops a recursive method for computing moments of 2D objects described by elliptic Fourier descriptors (EFD). Green´s theorem is utilized to transform 2D surface integrals into 1D line integrals and EFD description is employed to derive recursions for moments computations. Experiments are performed to quantify the accuracy of our proposed method. Comparison with Bernstein-Bézier representations is also provided.
