“…Both approaches generate the line response map by using the characteristics of a line with a convex intensity profile distinct from the background of the image. The line is then detected from the line response map using a random sample consensus (RANSAC) [ 8 , 9 , 11 , 12 , 17 , 18 ], Hough transform [ 3 , 4 , 5 , 6 , 7 , 16 , 19 , 20 ], or Radon transform [ 2 , 13 ]. The process described above has been successful in many line detection studies.…”
