+##List of Known Dependencies
+###ORB-SLAM2 version 1.0
+
+In this document we list all the pieces of code included by ORB-SLAM2 and linked libraries which are not property of the authors of ORB-SLAM2.
+
+
+#####Code in **src** and **include** folders
+
+* *ORBextractor.cc*.
+This is a modified version of orb.cpp of OpenCV library. The original code is BSD licensed.
+
+* *PnPsolver.h, PnPsolver.cc*.
+This is a modified version of the epnp.h and epnp.cc of Vincent Lepetit. 
+This code can be found in popular BSD licensed computer vision libraries as [OpenCV](https://github.com/Itseez/opencv/blob/master/modules/calib3d/src/epnp.cpp) and [OpenGV](https://github.com/laurentkneip/opengv/blob/master/src/absolute_pose/modules/Epnp.cpp). The original code is FreeBSD.
+
+* Function *ORBmatcher::DescriptorDistance* in *ORBmatcher.cc*.
+The code is from: http:https://graphics.stanford.edu/~seander/bithacks.html#CountBitsSetParallel.
+The code is in the public domain.
+
+#####Code in Thirdparty folder
+
+* All code in **DBoW2** folder.
+This is a modified version of [DBoW2](https://github.com/dorian3d/DBoW2) and [DLib](https://github.com/dorian3d/DLib) library. All files included are BSD licensed.
+
+* All code in **g2o** folder.
+This is a modified version of [g2o](https://github.com/RainerKuemmerle/g2o). All files included are BSD licensed.
+
+#####Library dependencies 
+
+* **Pangolin (visualization and user interface)**.
+https://github.com/stevenlovegrove/Pangolin
+
+* **OpenCV**.
+BSD licensed.
+
+* **Eigen3**.
+For versions greater than 3.1.1 is MPL2, earlier versions are LGPLv3.
+
+* **BLAS** (required by g2o).
+[Freely-available software](http:https://www.netlib.org/blas/#_licensing).
+
+* **LAPACK**(required by g2o).
+BSD licensed. 
+
+* **ROS (Optional, only if you build Examples/ROS)**.
+BSD licensed. In the manifest.xml the only declared package dependencies are roscpp, tf, sensor_msgs, image_transport, cv_bridge, which are all BSD licensed.
