Analysing Error of Fit Functions for Ellipses
Paul L. Rosin · 1996
We describe several established error of fit (EOF) functions for use in the least square fitting of ellipses, and introduce a further four new EOFs.Four measures are given for assessing the suitability of such EOFs, quantifying their linearity, curvature bias, asymmetry, and overall goodness.These measures enable a better understanding to be gained of the individual merits of the EOF functions.
