From: A variant of the Hough Transform for the combined detection of corners, segments, and polylines
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 =3 (distance between ground truth and detected points). This ratio quantifies the hit rates of the three corner detection methods. In general, clearly higher hit rates can be observed when using the proposed method in the large majority of the test images
