Install OpenCV on Ubuntu

     
         
          I have installed OpenCV succesfully with most of the options in Ubuntu as below


         1.  Install the required packages
           

apt-get install build-essential doxygen imagemagick python-pip python-dev cmake ant default-jdk libgphoto2-dev zlibc  libdc1394-22-dev libgstreamer1.0-dev gstreamer1.0-plugins-base gstreamer1.0-tools gstreamer0.10 libv4l2rds0 jasper libjasper-dev libjasper1 libjasperreports-java 

libtiff-tools libtiff-opengl libtiff5 libtiff5-dev libtiffxx5 python-libtiff libjpeg8-dev liblapack3 libjpeg-turbo8-dev  liblzma-dev python-numpy libjpeg-dev libblas3 python-imaging  libpng-dev libgtk-3-dev gstreamer-tools gstreamer1.0 libv4l-dev libavcodec-dev libavformat-dev libswscale-dev 

libavresample-dev libtbb-dev python3-dev python3-numpy qt-sdk python3-pip yasm libvtk5-dev vtk-examples tcl-vtk python-vtk libvtk-java libvtk5.8-qt4 glogg libgtkglext1-dev libavformat-extra-54 dctrl-tools libilmbase-dev libopenexr-dev libptexenc1 luatex libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libopencore-amrnb-dev libopencore-amrwb-dev libxine2-dev zlib1g-dev libwebp-dev libgdal-dev libeigen3-dev python-tk python3-tk qt5-default libvtk6-dev libavformat-extra-54 libxkbcommon-x11-dev libvncserver0 x11vnc-data x11vnc

        2.  Update the packages and upgrade the cmake to >= 2.8.12.2
           
              apt-get update
              apt-get upgrade cmake

         3.  Install Python package

               pip install numpy
               pip install -U pip setuptools

        4.   Fix the issues before installing opencv
           
              a. Issue:
                 Could NOT find PythonLibs (missing:  PYTHON_INCLUDE_DIRS)
                 (found suitable exact version "2.7.6")
                 Solution:
                 Some last version of Ubuntu installs Python 3.4 by default and 
                 the CMake version from Ubuntu (2.8) only searches up to Python 3.3.
                 Try to add set(Python_ADDITIONAL_VERSIONS 3.4) before the 
                 find_package statement.
                 /apps/build/opencv-3.1.0/CMakeLists.txt
                 Remember to clean CMakeCache.txt too.

              b. Issue:
                  Looking for linux/videodev.h - not found
                  Solution:
                  sudo apt-get install libv4l-dev
                  cd /usr/include/linux
                  sudo ln -s ../libv4l1-videodev.h videodev.h

              c. Issue:
                  Looking for ffmpeg/avformat.h - not found
                 Solution:
                 cd /usr/include/
                 sudo mkdir ffmpeg  
                 sudo cp /usr/include/libavcodec/*  /usr/include/ffmpeg/
                 sudo cp /usr/include/libavformat/*  /usr/include/ffmpeg/
                 sudo cp /usr/include/libswscale/*  /usr/include/ffmpeg/

        5.  Install Tesseract if you want to configure with OpenCV

        6.  Download the OpenCV source
             curl -L -o opencv-3.1.0.tar.gz https://github.com/Itseez/opencv/archive/3.1.0.tar.gz
             tar -xzf opencv-3.1.0.tar.gz

             Also download opencv_contrib

       7. Configure OpenCV
         
            cd opencv-3.1.0
            mkdir release
            cd release
            cmake -D CMAKE_BUILD_TYPE=Release -D BUILD_EXAMPLES=ON -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=ON -DPLANTUML_JAR=<Full_Path>/plantuml.jar -DOPENCV_EXTRA_MODULES_PATH=<Full_Path>/opencv_contrib/modules -D WITH_TBB=ON -DWITH_QT=ON -DWITH_OPENGL=ON -DFORCE_VTK=ON -DWITH_GDAL=ON -DWITH_XINE=ON  ..

           make -j7

           make install

           sudo ldconfig

     8.  Test installation 

           cd <OpenCv_Src>/<Build_Dir>/bin
           cp <OpenCv_Src>/samples/java/clojure/simple-sample/resources/images/lena.png .
           cp <OpenCv_Src>/samples/data/lena.jpg .
           ./opencv_test_core

           If successful you will see as below:
