Abstract
Circuit drawing is an important task especially in undergraduate courses such as electronics and digital
systems. To improve human computer interaction, we have developed recognition system for the hand written circuit and
its components. Here, the scanned image of a diagram is pre-processed to remove noise and converted to binary level and
morphological operations are applied to obtain a clean, connected representation using thinned lines. The diagram
comprises of nodes, connections and components. Using appropriate thresholds on a spatially varying object pixel
density, nodes and components of the image are segmented. By the use of shape feature and Support Vector Machine
(SVM) classifier components and nodes are classified.
