Direct least squares fitting of ellipses

  title={Direct least squares fitting of ellipses},
  author={Andrew W. Fitzgibbon and Maurizio Pilu and Robert B. Fisher},
This work presents a new efficient method for fitting ellipses to scattered data. Previous algorithms either fitted general conics or were computationally expensive. By minimizing the algebraic distance subject to the constraint 4 2 1 the new method incorporates the ellipticity constraint into the normalization factor. The new method combines several advantages: (i) It is ellipse-specific so that even bad data will always return an ellipse; (ii) It can be solved naturally by a generalized… CONTINUE READING
