     * detected points with their affine invariant elliptic region and to compute
     * the feature descriptors on the regions after warping them into circles.
     *
     * The interface is equivalent to REF: Feature2D, adding operations for
     * REF: Elliptic_KeyPoint "Elliptic_KeyPoints" instead of REF: KeyPoint "KeyPoints".
