WebDec 31, 2014 · After introducing errors-in-variables (EIV) regression analysis and its history, the book summarizes the solution of the linear EIV problem and highlights its main geometric and statistical properties. It next describes the theory of fitting circles by least squares, before focusing on practical geometric and algebraic circle fitting methods.
WebWe recommend Taubin fit. Kasa fit (the simplest and fastest fit, but biased toward smaller circles when an incomplete arc is observed) Pratt fit (more robust than Kasa fit, but a little slower) Taubin fit (similar to Pratt fit, but a bit faster and a bit more accurate) (perhaps the best algebraic circle fit) Hyper fit (a new fit: a combination ...
