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 d (total number of detected segments) for the whole dataset considering d S =2 (distance between ground truth and detected line segments). The differences among the three methods when reducing d S become more significant, showing the greater accuracy of HT3D compared with the other two methods
