  annote = {We propose a novel unified approach for homography
    estimation from two or more correspondences of local elliptical
    features. The method finds a homography defined by first-order
    Taylor expansions at two (or more) points. The approximations are
    affine transformations that are constrained by the
    ellipse-to-ellipse correspondences. Unlike methods based on
    projective invariants of conics, the proposed method generates
    only a single homography model per pair of ellipse
    correspondences. We show experimentally, that the proposed method
    generates models of precision comparable or better than the
    state-of-the-art at lower computational costs.},
