Circuit diagrams, or schematics, are a standard means of representing electronic circuits. While this format is excellent for conveying much of the relevant circuit details in visual form to scientists, engineers, and hobbyists, it is not able to be readily manipulated or processed by computers. Having a circuit in computer useable form is required for such applications as automated layout of printed circuit boards, simulating the electrical characteristics of the circuit, and maintaining a database of circuits or circuit modules. In all of these, a suitable representation of the circuit is as a netlist, that is as a list of components and their interconnections. This project is examines the feasibility of using image analysis for automatically obtaining netlists from circuit schematics in printed form. This process involves recognising the various electronic component symbols within the schematic and determining their connectivity….
