A new ellipse detection algorithm using major axis of the ellipse and dual points method

A new ellipse detect method is presented based on major axis of the ellipse,which uses major axis of the ellipse to calculate four ellipse parameters and accumulates the length information for minor axis of the ellipse.Using dual points method to validate whether this is a major axis of the ellipse.Experimental results demonstrate that this method is faster than the former method based on major axis of the ellipse.
