The newer techniques promise consistency, unbiasedness, or hyper-accuracy, but our experiments reveal that in practice the performance of these estimators is difficult to distinguish from the performance of established estimators. Since the newer techniques could potentially be extended to other estimation problems, we discuss what implications our experimental findings have for solving more general multipleview geometry estimation problems.en© 2012 IEEEApproximation methodscost functionequationsmaximum likelilhood estimationshapetrainingConference paper002012637610.1109/DICTA.2012.64117220003163184000582-s2.0-8487434508520769Szpak, Z.
