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.
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.
