Many approaches have been suggested to do ellipse detection. Recently, a symmetric-axis method has been proposed to determine the center of an ellipse but the other parameters are determined otherwise. In this paper, a consistent symmetric axis method is proposed that utilizes the information inherent in the symmetric axes throughout the entire process to compute all of the parameters. Convergence of the numerical procedure is assured. Since the determination of the symmetric axes involves a set of points on the ellipse, the procedure is robust. Experiments with interacting ellipses, defective ellipses, and real objects indicate the effectiveness of the proposed method both theoretically and practically
