  • Abstract
    Fourier descriptors (FDs) are one of the efficient tools for discrimination of planar shapes. The problem of achieving a unique normalisation of the given set of FDs has not been solved satisfactorily. An improved method for normalisation which has applicability over a wider range of shapes is suggested in the letter. A sufficient condition for the axial symmetry of a contour is also given.
