  • segment line detector (lsd)
  • edge drawing line detector (edlines)
  • hough line detector (standard and probabilistic)

All original dependencies have been removed. Code could be run independently:

  • line segment detector with a scale in vertical and horizontal direction in boundingbox, respectively
  • edge drawing line detector with a scale in vertical and horizontal direction in boundingbox, respectively
  • hough line detector(standard and probabilistic) with a scale in vertical and horizontal direction in boundingbox, respectively
