Feature extraction from line drawing images
This paper describes progress towards an automatic system for extracting line features from line drawing images. A semi-automatic system for tracking lines and for building features from the resulting line fragments has been developed. Operator intervention is required to guide the feature building when ambiguities arise. A knowledge based system, which works alongside the semi-automatic system, can execute some of the decision making tasks in place of the operator and as the knowledge base is increased the need for operator intervention will diminish.
