- python 3
- CMake (tested with version 3.12.2)
- Boost.Python (to compile the python wrapper, tested with version 1.66)
- OpenCV (to compile the example convert_3d_texture_cpp)

cd python_wrapper

To import the package set the following environmental variable:
export PYTHONPATH="..package location../ext3DLBP/python_wrapper/build:$PYTHONPATH"
To run the unit tests:
./test_functional/run.sh
#include "ext3DLBP.hpp"
#include <iostream>
#include <array>
int main(int argc, char* argv[]){
Array3D<int,3,3,3> array = {{
{{{0,0,0},{0,0,0},{0,0,0}}},
{{{0,0,0},{0,0,0},{0,0,0}}},
{{{0,0,0},{0,0,0},{0,0,0}}}
}};
double mur = 128.0;
int V = 3;
ext3DLBP::NI_RD_CI_LBP<P42g, R1> NI_RD_CI_lbp(mur, V);
Array1D<int,3> NI_RD_CI_code = NI_RD_CI_lbp.convert(array);
std::cout << "codes(NI,RD,CI) = (" << NI_RD_CI_code[0] << "," << NI_RD_CI_code[1] << "," << NI_RD_CI_code[2] << ")\n";
return 0;

lbp = ext3DLBPpy.NI_RD_CI_LBP_P42g_R1(mur, V)
LBPcodes = lbp.convert(array)

We suggest installing Boost.Python from source as we need to include some header files in our library:
cd $HOME
wget https://dl.bintray.com/boostorg/release/1.66.0/source/boost_1_66_0.tar.bz2
tar --bzip2 -xf boost_1_66_0.tar.bz2
cd boost_1_66_0
./bootstrap.sh --with-python=python3
sudo ./b2 install
sudo ldconfig
cd $HOME
- If you have a message similar to this one:
failed updating 66 targets...fatal error: pyconfig.h: No such file or directorythen you may want to try this:
./bootstrap.sh --with-python=python3 --with-python-version=3.5m
sudo ./b2 install
sudo ldconfig
another option would be to modify line 542 of file tools/build/src/tools/python.jam from this:
includes ?= $(prefix)/include/python$(version) ;
to this:
includes ?= $(prefix)/include/python$(version)m ;
./bootstrap.sh --with-python=python3
sudo ./b2 install
sudo ldconfig
- Another version of Boost is clashing with the new one. If it is the case for you we suggest removing the old version and re-install the new one. HINT: after compiling the core module, type
ldd core.soto see which boost.python was used.
We first need to install some packages:
sudo apt-get install build-essential
sudo apt-get install git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev libv4l-dev libxvidcore-dev libavresample-dev libx264-dev
sudo apt-get install libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
then:
cd ${HOME}
git clone https://github.com/opencv/opencv.git
git clone https://github.com/opencv/opencv_contrib.git
cd opencv_contrib
cd ../opencv
mkdir build
cd build
cmake -DWITH_FFMPEG=ON -DOPENCV_EXTRA_MODULES_PATH=${HOME}/opencv_contrib/modules -DWITH_CUDA=OFF -DBUILD_TIFF=ON -DBUILD_opencv_java=OFF -DENABLE_AVX=ON -DWITH_OPENGL=ON -DWITH_OPENCL=ON -DWITH_IPP=ON -DWITH_TBB=ON -DWITH_EIGEN=ON -DWITH_V4L=ON -DWITH_VTK=OFF -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF -DCMAKE_BUILD_TYPE=RELEASE -DBUILD_opencv_python2=OFF -DCMAKE_INSTALL_PREFIX=$(python3 -c "import sys; print(sys.prefix)") -DPYTHON3_EXECUTABLE=$(which python3) -DPYTHON3_INCLUDE_DIR=$(python3 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") -DPYTHON3_PACKAGES_PATH=$(python3 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())") -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF -D WITH_GTK_2_X=ON -D BUILD_EXAMPLES=ON ..
then we suggest double-checking the report to make sure FFmpeg is detected:
-- General configuration for OpenCV 3.4.0-dev >===================================== -- Extra modules: -- Location (extra): /home/.../opencv_contrib/modules -- Version control (extra): 3.4.0
-- Video I/O: -- DC1394: NO -- FFMPEG: YES -- avcodec: YES (ver 56.60.100) -- avformat: YES (ver 56.40.101) -- avutil: YES (ver 54.31.100) -- swscale: YES (ver 3.1.101) -- avresample: YES (ver 2.1.0)
then:
make -j8
sudo make install
to verify OpenCV is correctly installed; open a terminal and type python then type:
import cv2
print(cv2.__version__)
