Detailed Description

template<class TInputImage, class TPrecision = double>
class otb::LineSegmentDetector< TInputImage, TPrecision >

this class implement a fast line detector with false detection control using the a contrario method

The implementation is based on the online version of the lsd documentation and code lsd 1.5. The OTB version use a 3x3 filter to compute the gradient(vs. 2x2 in the original implementation) and implements the density control, the NOTINIT status and the incremental rectangle optimisation.
