Hand Written Circuit Schematic Recognition
Journal Title: Scholars Journal of Engineering and Technology - Year 2014, Vol 2, Issue 5
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. Keywords: Component, Port, Contact, Circuit, Connection, Node, Support Vector Machine (SVM).
