It is based on Burns, Hanson, and Riseman method and use an a contrario validation approach (Desolneux, Moisan, and Morel). The algorithm was published by Rafael Gromponevon Gioi, Jérémie Jakubowicz, Jean-Michel Morel and Gregory Randall.

The given approach computes gradient and level lines of the image and detects aligned points in line support region. The application allows exporting the detected lines in a vector data.<h2>Parameters</h2><ul><li><b>[param] -in</b> <string> Input image on which lines will be detected.. Mandatory: True. Default Value: ""</li><li><b>[param] -out</b> <string> Output detected line segments (vector data).. Mandatory: True. Default Value: ""</li><li><b>[param] -elev</b> <string> This group of parameters allows managing elevation values. Supported formats are SRTM, DTED or any geotiff. DownloadSRTMTiles application could be a useful tool to list/download tiles related to a product.. Mandatory: True. Default Value: "0"</li><li><b>[param] -norescale</b> <boolean> By default, the input image amplitude is rescaled between [0,255]. Turn on this parameter to skip rescaling. Mandatory: False. Default Value: "True"</li><li><b>[param] -inxml</b> <string> Load otb application from xml file. Mandatory: False. Default Value: ""</li><li><b>[param] -outxml</b> <string> Save otb application to xml file. Mandatory: False. Default Value: ""</li></ul><h2>Limitations</h2>None<h2>Authors</h2>OTB-Team<h2>See Also</h2>On Line demonstration of the LSD algorithm is available here: http://www.ipol.im/pub/algo/gjmr_line_segment_detector/
