PyMaxflow

PyMaxflow is a Python library for graph construction and maxflow computation (commonly known as graph cuts).

The core of this library is the C++ implementation by Vladimir Kolmogorov, which can be downloaded from his homepage. Besides the wrapper to the C++ library, PyMaxflow offers

• NumPy integration,
• methods for fast construction of common graph layouts in computer vision and graphics,
• implementation of algorithms for fast energy minimization which use the maxflow method: the αβ-swap and the α-expansion.

Take a look at the PyMaxflow documentation.

Example layouts

PyMaxflow offers methods to easily build advanced network layouts with a few API calls. These are examples from layout_examples.py.

Installation

Open a terminal and write:

$ pip install PyMaxflow

Manual installation

Download the source code or clone the Github repository. Open a terminal and write:

$ cd path/to/PyMaxflow
$ python setup.py build
... lots of text ...

If everything went fine, you should be able to install the package with:
