Networks are among the central building blocks of many systems. Given a graph of a network, methods from graph theory enable precise investigation of its properties. Software for the analysis of graphs is widely available and has been applied to study various types of networks. In some applications, graph acquisition is relatively simple. However, for many networks data collection relies on images where graph extraction requires domain-specific solutions.

In this talk I will introduce NEFI, a tool based on well-known techniques from CV and image processing, which extracts graphs from suitable images of a wide range of networks originating in various domains.

NEFI is open source and available at
