Least-Squares Fitting Based on Euclidean Distances


In the above section, we have described three general techniques for solving linear least-squares problems, either unconstrained or constrained, based on algebraic distances. In this section, we describe why such techniques usually do not provide satisfactory results, and then propose to fit conics using directly Euclidean distances.
