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 Dependencies to the BIAS library have been removed and the code was tested with OpenCV3. PairWiseLineMatching still depends on ARPACKPP for the computation of eigenvalues and eigenvectors.

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