Requirements

• OpenCV 3

And the following python requirements:

• Theano
• Lasagne (Dev)
• numpy
• scipy
• flufl.lock
• parse
• h5py

which can be installed with

pip install -r requirements.txt

Usage

Build the shared library by

cd c-code/build
cmake ..
make

To run the test program simply

./run.sh

Note

This model was trained with SfM data (Piccadilly Circus dataset), which does not have strong rotation changes. Newer models work better in this case, which will be released soon. In the meantime, you can also use the models in the learn-orientation, benchmark-orientation.
