WebSep 20, 2012 · Abstract: Fitting straight lines and simple curved objects (circles, ellipses, etc.) to observed data points is a basic task in computer vision and modern statistics (errors-in-variables regression). We have investigated the problem of existence of the best fit in our previous paper (see Chernov et al. (2012)). Webbased on minimizing the mean square distance from the circle to the data points. Given n points (x i,y i), 1 ≤ i ≤ n, the objective function is deﬁned by F = Xn i=1 d2 i (1.1) where d i is the Euclidean (geometric) distance from the point (x i,y i) to the circle.
