dependence

1. We need CMake to configure the installation, GCC for compilation, Python-devel and Numpy for building Python bindings etc.

   • sudo apt-get install cmake
   • sudo apt-get install gcc g++

2. Next we need GTK support for GUI features, Camera support (v4l), Media Support (ffmpeg, gstreamer) etc.

   • sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev
   • sudo apt-get install libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev

3. to support gtk2

   • sudo apt-get install libgtk2.0-dev

4. to support gtk3

   • sudo apt-get install libgtk-3-dev

5. install ffmpeg

   • sudo apt install ffmpeg

install opencv

1. Download and unpack sources
   • wget -O opencv.zip https://github.com/opencv/opencv/archive/master.zip
   • wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/master.zip
   • unzip opencv.zip
   • unzip opencv_contrib.zip
   • mkdir -p build && cd build
   • cmake -DOPENCV_ENABLE_NONFREE:BOOL=ON -DWITH_FFMPEG=ON -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib-master/modules ../opencv-master
   • cmake --build .
   • sudo make install

install boost

boost is needed to run the code
 - sudo apt-get install libboost-dev

build

in the code root directory, 
    - mkdir build
    - cd build
    - cmake ..
    - make 
    - ./app
