To compile it, please type "mex mexlsdsar.c lsdsar.c", then you can run any demo file to test it.

There are three demo files:
    demo_purenoise: the number of false detections in pure noise image by LSDSAR is tested.
    demo_synthetic_image: line segment detection results in synthetic images by LSDSAR are given.
    demo_real_image: line segment detection results in real SAR images by LSDSAR are given.

I would be grateful to receive any advices or possible errors in the source code.

==Introduction
==------------
==
==LSD is an implementation of the Line Segment Detector on digital
==images described in the paper:
==
==  "LSD: A Fast Line Segment Detector with a False Detection Control"
==  by Rafael Grompone von Gioi, Jeremie Jakubowicz, Jean-Michel Morel,
==  and Gregory Randall, IEEE Transactions on Pattern Analysis and
==  Machine Intelligence, vol. 32, no. 4, pp. 722-732, April, 2010.
==
==and in more details in the CMLA Technical Report:
==
==  "LSD: A Line Segment Detector, Technical Report",
==  by Rafael Grompone von Gioi, Jeremie Jakubowicz, Jean-Michel Morel,
==  Gregory Randall, CMLA, ENS Cachan, 2010.
==
==The version implemented here includes some further improvements as
==described in the IPOL article of which this file is part:
==
==  "LSD: a Line Segment Detector" by Rafael Grompone von Gioi,
==  Jeremie Jakubowicz, Jean-Michel Morel, and Gregory Randall,
==  Image Processing On Line, 2012. DOI:10.5201/ipol.2012.gjmr-lsd
