1. A method of recognizing an ear by locating an invariant point in a representation (X) of ear geometry, the method comprising the steps of:

  • creating a polar representation (e[θ

    , ρ

    ]) of the ear geometry;

    transforming the polar representation by means of a Fourier transformation, wherein a transformed (E[Θ

    , P]) polar representation is created; and

    sampling the transformed polar representation using a number of samples (n) to create a feature vector (XF) comprising a number (m) of feature components.
