NEFI2 is a Python tool created to extract networks from images.

Given a suitable 2D image of a network as input, NEFI outputs a mathematical representation of the structure of the depicted network as a weighted undirected planar graph. Representing the structure of the network as a graph enables subsequent studies of its properties using tools and concepts from graph theory.

Installation on Linux

Make sure you have your Python 3.4 installed before performing the steps below.

• git clone https://github.com/LumPenPacK/NetworkExtractionFromImages.git
• cd "NetworkExtractionFromImages"
• ./install.sh
• Install PyQt5 using you default package manager.
• Next, you'll need to compile OpenCV 3.1.0 for your Python 3.

    git clone https://github.com/Itseez/opencv.git
    git checkout 3.1.0a
    mkdir release
    cd release
    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=$(python3 -c "import sys; print(sys.prefix)") -D PYTHON_EXECUTABLE=$(which python3) ..
    make -j4
    sudo make install

If everything goes well, you can run NEFI2 by typing in console nefi2.
