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 =3 (distance between ground truth and detected points). A low value of this ratio for one detector in relation to other methods is indicative of a high number of false alarms. As it can be observed in this figure, the ratio remains almost constant in the three methods for most of the test images, which denotes similar rates of false alarms in the three detectors
