Fast and Numerically Stable Circle Fit

H. Abdul-Rahman, N. Chernov
2013 Journal of Mathematical Imaging and Vision  
We develop a new algorithm for fitting circles that does not have drawbacks commonly found in existing circle fits.  ...  Our fit achieves ultimate accuracy (to machine precision), avoids divergence, and is numerically stable even when fitting circles get arbitrary large.  ...  Since H is a 2 × 2 matrix, its eigendecomposition can be computed by fast direct formulas (without using matrix algebra functions).  ...
