Python library for creating flow networks and computing the maxflow/mincut (aka graph-cuts for Python)

PyMaxflow is a Python library for graph construction and maxflow computation (commonly known as graph cuts) as described in Boykov04. 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.
