In this paper we review and analyze existing least squares orthogonal distance fitting techniques in a general numerical optimization framework. Two new geometric variant methods (GTDM and CDM) are proposed. The geometric meanings of existing and modified optimization methods are also revealed}, publisher = {Springer-Verlag Berlin Heidelberg}, url = {http://approjects.co.za/?big=en-us/research/publication/revisit-least-squares-orthogonal-distance-fitting-parametric-curves-surfaces/}, }
