Ratio between NEp c (number of correct matchings between ground truth and detected points) and NEp d (total number of detected points) for the whole dataset considering d Ep =2 (distance between ground truth and detected points). No significant variations of this ratio can be observed among the three methods when reducing d Ep . This indicates a similar accuracy of the compared methods
