Installing OpenCV 3.2.0 with contrib modules in Ubuntu 16.04 LTS

UPDATE: You can also install OpenCV 4.5.0 in Ubuntu 20.04LTS.

OpenCV 3.2.0 has been out for a while and contains many improvements and exciting new features, so it’s time to update this guide using the latest Ubuntu 16.04LTS.

A big change in OpenCV 3.2.0 is that now many of the newest algorithms now reside separately in the contrib repository.

Some of these modules include Face Recognition, RGB-Depth processing, Image Registration, Saliency, Structure From Motion, Tracking, and much more.

So let’s install OpenCV 3.2.0 with the contrib modules and other good stuff by executing the following code on the command line:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff5-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen3-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev default-jdk ant libvtk5-qt4-dev
cd ~
mkdir opencv
cd opencv
wget https://github.com/opencv/opencv/archive/3.2.0.tar.gz
tar -xvzf 3.2.0.tar.gz
wget https://github.com/opencv/opencv_contrib/archive/3.2.0.zip
unzip 3.2.0.zip
cd opencv-3.2.0

But before we build it, we need to fix one problem currently present in the contrib modules, specifically in the freetype module, which allows you to draw UTF-8 strings. If you are getting an error similar to ImportError: /usr/local/lib/libopencv_freetype.so.3.2: undefined symbol: hb_shape, this will fix it:

sed -i 's/${freetype2_LIBRARIES} ${harfbuzz_LIBRARIES}/${FREETYPE_LIBRARIES} ${HARFBUZZ_LIBRARIES}/g' ../opencv_contrib-3.2.0/modules/freetype/CMakeLists.txt

Since now that problem is solved, now we are ready to build OpenCV.

mkdir build
cd build
cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_VTK=ON .. -DCMAKE_BUILD_TYPE=RELEASE -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.2.0/modules ..
make
sudo make install
echo '/usr/local/lib' | sudo tee --append /etc/ld.so.conf.d/opencv.conf
sudo ldconfig
echo 'PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig' | sudo tee --append ~/.bashrc
echo 'export PKG_CONFIG_PATH' | sudo tee --append ~/.bashrc
source ~/.bashrc

Now you should be able to compile with the OpenCV libraries, including the contrib repositories.

For example, let’s compute some Fine-Grained Saliency, which is available in the saliency module of the contrib repository:

cd ~
mkdir saliency
cd saliency
cp ../opencv/opencv_contrib-3.2.0/modules/saliency/samples/computeSaliency.cpp .
cp ../opencv/opencv-3.2.0/samples/data/Megamind.avi .
g++ -o computeSaliency `pkg-config opencv --cflags` computeSaliency.cpp `pkg-config opencv --libs`
./computeSaliency FINE_GRAINED Megamind.avi 23

  1. xs.yan says

    After installing opencv I run the python samples code:

    cd /samples/python/
    python asift.py

    and I get the following error:

    Traceback (most recent call last):
    File “asift.py”, line 26, in
    import cv2
    ImportError: /usr/local/lib/libopencv_freetype.so.3.2: undefined symbol: hb_shape

    Running other python samples will get the same error. I haven’t found the answer in google. How do I fix it?

    have you solve this problem about “undefined symbol: hb_shape”

  3. samontab says

    Yeah, I updated the post with the fix to it. The problem was an incorrect file in the contrib module.

    To fix it, in the file ../opencv_contrib-3.2.0/modules/freetype/CMakeLists.txt in line 22, you need to change the text ${freetype2_LIBRARIES} ${harfbuzz_LIBRARIES} to ${FREETYPE_LIBRARIES} ${HARFBUZZ_LIBRARIES}

    Thank you so much, a casual 2 hour install time was well worth it.
    I now have the power!

    Hey Vasco, that looks like you don’t have enough memory in that system.

  8. Stevux says

    The contrib modules are actually compiled? Because you compile computeSaliency separately it would seem that are not compiled automatically…

    December 27, 2017, 1:24 am
  9. samontab says

    Yeah, the contrib modules are actually compiled automatically.

    computeSaliency is just an example program that uses the already compiled library module called saliency.

    Make sure you’re using the correct API. Check out the stereo tutorials from here:
