In this paper a method to detect the electrical circuit elements from the scanned images of electrical drawings is proposed.
The method, based on histogram analysis and mathematical morphology, detects the circuit elements, for example, circuit
components, wires, and generates a connectivity matrix which may be used to find similar, but spatially different looking
circuit using graph isomorphism. The work may also be used for vectorization of the circuit drawings utilising the information
on the segmented circuit elements and corresponding connectivity matrix. The novelty of the method lies in its
simplicity and adaptability to work with a tolerable skewed image and the capability to segment symbols irrespective of
their orientation. The proposed method is tested over a data-set containing more than one hundred scanned images of a
variety of electrical drawings. Some of the results are presented in this paper to show the efficacy and robustness of the
