ABSTRACT:
A method for determining a circle in an image is disclosed. The method extracts a first pair of edge points along an x-axis of the image, extracts a second pair of edge points along a y-axis of the image, determines an intersection of a first and second line extending perpendicular from a pair of midpoints of the first and second pair of edge points respectively, and determines a radius from the intersection to any edge point.
