Ratio between NEp c (number of correct matchings between ground truth and detected points) and NEp g (number of ground truth points) for the whole dataset considering d Ep =2 (distance between ground truth and detected points). The hit rates of the proposed method remain higher than the hit rates of the other two methods when reducing d Ep . No significant differences in the accuracy of the three methods can be appreciated in comparison to greater values of d Ep
