Description Existing linear methods for estimating homographies, rely on coor-dinate normalization, to reduce the error in the estimated homog-raphy. Unfortunately, the estimated homography depends on the choice of the normalization. The proposed extension to the (lin-ear) Taubin estimator is the perfect substitute for such methods, as it does not rely on coordinate normalization, and produces homogra-phies whose error is consistent with existing methods. Also, unlike existing linear methods, the proposed Taubin estimator is theoreti-cally unbiased, and unaffected by similarity transformations of the correspondences in the two views. In addition, it can be adapted to estimate other quantities such as trifocal tensors. Index Terms — Homography, Taubin estimator 1.
