An Algorithm for the Least Square-Fitting of Ellipses
Nicola Greggio, Alexandre J. M. Bernardino, Cecilia Laschi, Paolo Dario, José Santos-Victor · 2010
In this paper we propose a new algorithm for the least square fitting of ellipses from scattered data. Originally based on the one proposed by Fitzgibbon et Al in 1999, our procedure is able to overcome the numerical instability of that algorithm. We test our approach versus the latter and another approach with different ellipses. Then, we present and discuss our results.
