From: A variant of the Hough Transform for the combined detection of corners, segments, and polylines
Ratio between NS c (number of detected segments matching the ground truth data) and NS g (total number of segments of the ground truth data) for the whole dataset considering d S =3 (distance between ground truth and detected line segments). This ratio measures the hit rates of the three methods for every test image. In general, it is possible to observe a greater correspondence of the results provided by the proposed method with the ground truth data
