Connector Semantics for Sketched Diagram Recognition

Freeman, I.J. and Plimmer, B.

    Comprehensive interpretation of hand-drawn diagrams is a long-standing challenge. Connectors (arrows, edges and lines) are important components of many types of diagram. In this paper we discuss techniques for syntactic and semantic recognition of connectors. Undirected graphs, digraphs and organization charts are presented as exemplars of three broad classes that encompass many types of connected diagram. Generic techniques have been incorporated into the recognition engine of InkKit, an extensible sketch toolkit, thus reducing the development costs for sketch tools.
