libcnn is a modular deep learning libraray, useful for robotics and computer vision. It is being developed by Robotics and Multi-perception Lab of City Univerisity of Hong Kong.

Here is a quick version to help you get started with the library.

The library has a light dependancy list:

• Eigen vesion 3, a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.
• boost version 1.49, peer-reviewed portable C++ source libraries.

The library was compiled on Ubuntu

mkdir build
cd build
cmake ..
make
sudo make install (optional)

We show an example of pixel-wise classification: scene-labelling.
The example used semantically-augmented make3d dataset. The following assumes that you have already successfully done the above.

cd build
./train (training)
./validate (testing)

Here are several pixel-wise classification results of semantically-augmented make3d dataset
