DOI: 10.1117/1.jrs.12.036021
Abstract: Abstract. To overcome the illposed problems existing in small baseline subsets deformation, the Liu-type estimator is used to improve the accuracy of calculation. The Liu-type estimator introduces parameter d to improve the fitting and statistical… read more here.
