Abstract
A method for recognizing a reference point associated with a fiducial marker including the steps of: obtaining or receiving image data of the fiducial marker; determining the degree of which the image data of the fiducial marker is aligned with one or more reference images; of which if the degree of alignment is determined to be less than an acceptable threshold predicting a set of coordinates of the reference point associated with the fiducial marker; incorporating the set of coordinates with the image data to form a modified image data; and determining the degree of which the modified image data of the fiducial marker is aligned with one or more reference images.
