# Line_Segment_Detector
C/C++ code for line segment detector (LSD)

Modified by : Suryansh Kumar

If you are using this code you should refer to
[1]. Rafael Grompone von Gioi, Jérémie Jakubowicz, Jean-Michel Morel, and Gregory Randall, LSD: a Line Segment Detector, Image Processing On Line, 2 (2012), pp. 35–55.
Its c code is available at http://www.ipol.im/pub/art/2012/gjmr-lsd/

However, its written in c for .pgm image format. Keeping in mind the application of line segment detection in robot vision. I have modified it to use this 
robust algorithm for .jpg format. So, that you can easily integrate with your ROS repository or other vision or image processing related codes.
