This library is an implementation of LBD descriptors developed by Lilian Zhang and Reinhard Koch: http://www.sciencedirect.com/science/article/pii/S1047320313000874

The original code was written by Lilian Zhang and can be found here: http://www.mip.informatik.uni-kiel.de/tiki-index.php?page=Lilian+Zhang

To extract edge and lines, this library implements the EDLines Algorithm and the Edge Drawing detector: http://www.sciencedirect.com/science/article/pii/S0167865511001772 http://www.sciencedirect.com/science/article/pii/S1047320312000831

All original dependencies except Opencv have been removed and the code has been optimized for Opencv 2.4.x PairWiseLineMatching has not been touched and it still needs original dependencies, because the aim of this porting was to match descriptors with Opencv matchers.

During the 2014 GSoC a binarized version of these descriptors with a dedicated matcher implementation has been included into opencv_contrib:
